+ * Program:	Routines to support file browser in pico and Pine composer
+ *
+ *
+ * NOTES:
+ *
+ *   Misc. thoughts (mss, 5 Apr 92)
+ * 
+ *      This is supposed to be just a general purpose browser, equally
+ *	callable from either pico or the pine composer.  Someday, it could
+ * 	even be used to "wrap" the unix file business for really novice 
+ *      users.  The stubs are here for renaming, copying, creating directories,
+ *      deleting, undeleting (thought is delete just moves files to 
+ *      ~/.pico.deleted directory or something and undelete offers the 
+ *      files in there for undeletion: kind of like the mac trashcan).
+ *
+ *   Nice side effects
+ *
+ *      Since the full path name is always maintained and referencing ".." 
+ *      stats the path stripped of its trailing name, the unpleasantness of 
+ *      symbolic links is hidden.  
+ *
+ *   Fleshed out the file managements stuff (mss, 24 June 92)
+ *

+ *
+ *  Notes: These routines aren't incorporated yet, because the composer as

+ *         be implemented in later releases of PINE.  See the notes in 
+ *         pico.c concerning what needs to be done ....
+ *
+ *  - untabled 01/30/90
+ *
+ *  Notes: Installed header line editing, with wrapping and unwrapping, 
+ *         context sensitive help, and other mail header editing features.
+ *
+ *  - finalish code cleanup 07/15/91
+ * 
+ *  Notes: Killed/yanked header lines use emacs kill buffer.
+ *         Arbitrarily large headers are handled gracefully.
+ *         All formatting handled by FormatLines.

+ * 
+ *      There could to be something here to resolve cur_l and top_l
+ *      reasonably into the new linked list for this entry.  
+ *
+ *      The reason this would mostly work without it is resolve_niks gets
+ *      called for the most part in between fields.  Since we're moving
+ *      to the beginning or end (i.e. the next/prev pointer in the old 
+ *      freed cur_l is NULL) of the next entry, we get a new cur_l
+ *      pointing at a good line.  Then since top_l is based on cur_l in
+ *      NewTop() we have pretty much lucked out.
+ * 
+ *      Where we could get burned is in a canceled exit (ctrl|x).  Here
+ *      nicknames get resolved into addresses, which invalidates cur_l
+ *      and top_l.  Since we don't actually leave, we could begin editing
+ *      again with bad pointers.  This would usually results in a nice 
+ *      core dump.
+ *
+ *      NOTE: The mangled argument is a little strange. It's used on both
+ *      input and output. On input, if it is not set, then that tells the
+ *      builder not to do anything that might take a long time, like a
+ *      white pages lookup. On return, it tells the caller that the screen
+ *      and signals may have been mangled so signals should be reset, window
+ *      resized, and screen redrawn.

+ *
+ *      There are very limited number of flat ctrl-key bindings left, and

+ *      invoking an alternate editor in the composer and necessary funcs

+ *	The plan is to allocate small blocks in the local heap and
+ *	large blocks in the global heap.  The intention is to keep
+ *	the number of global allocations to a minimum.
+ *
+ *	The boundry between small memory and large memory is
+ *	controld by the constant SMALL_MEM_BOUNDRY.  Blocks smaller
+ *	than SMALL_MEM_BOUNDRY go into the local heap.  This should
+ *	be set large enough to capture the majority of small memory
+ *	blocks in the local heap.  But if it is too large, the local 
+ *	heap will fill up and we will end up allocating a lot of small
+ *	blocks in the global heap.
+ *
+ *	Unfortunatly, pine seems to need a large stack.  With the
+ *	stack, some global data, and the heap all cramed in to a 64K
+ *	segment we end up with a heap that is smaller than ideal.
+ *	This could be improved by reducing the size of the stack, or
+ *	by moving the heap to a seperate memory block.  I did a little
+ *	work on moving the heap, but was not successful.  My attepts
+ *	can be seen in the function MemATest().
+ *
+ *	Currently (7/8/94) I've set the stack to 32K (in pine/makefile.win),
+ *	the heap to 12K, and the small memory boundry to 32 bytes.
+ *	Statistics on pine memory allocation suggest that it would be better
+ *	to have a 25K local heap and a 95 byte small memory boundry.
+ *
+ *	Statistics on memory use can be gathered by logging memory debugging
+ *	to a file, then running the following awk script:
+ *
+
+  # mem.awk
+  #
+  #	Looks through log and find blocks that were allocated but not
+  #	freed uses block id numbers, rather than addresses, since this is
+  #	more accurate (and since this is what block ids exist!)
+  #
+  #	awk may run out of memory if the logfile gets too big.  If this
+  #	happens, then another strategy will be needed...

+                       those in list return value from list.  Nearly identical
+		       to Pine's ESCKEY structure.
+        help   -- Arrary of strings for help text in bottom screen lines
+        flags  -- flags
+
+  Result:  editing input string
+            returns -1 unexpected errors
+            returns 0  typed CR or pressed "OK"
+            returns 1  typed ESC or pressed "Cancel"
+            returns 3  typed ^G or PF1 (help)
+            returns 4  typed ^L for a screen redraw

+
+  WARNING: Care is required with regard to the escape_list processing.
+           The passed array is terminated with an entry that has ch = -1.
+           Function key labels and key strokes need to be setup externally!
+	   Traditionally, a return value of 2 is used for ^T escapes.
+		   
+		   
+  Note About Help:  We don't get the help text on the first call.  If we
+	  want help text we have to return 3.  We'll get called again
+	  with help text.  To make it look good, we want to display
+	  this the second time we're called.  But we don't want to
+	  display the help text every time we're called with help
+	  text.  To know the difference we set gDoHelpFirst when
+	  exiting to request help text.  If this is set then we
+	  display help.  If not, then no help.

+ * into the config file, we use the canonical_name (middle column). So if
+ * the user chooses green from the menu we write color010 in the config
+ * file. [This has changed. Now we put the RGB value in the config file
+ * instead. We leave this so that we can interpret color010 in the config
+ * file from old versions of pine.]
+ * We display that as green later. The xterm also displays that as
+ * green, because the bright green (color010) on the xterm is what we want
+ * to consider to be green, and the other one (color002) is dark green.
+ * And dark green sucks.
+ * On the PC we only use the first 11 colors in this table when giving the
+ * user the set color display, since the last eight are repeats.

+ *
+ *	Scrolling in the TTY window is complicated by the way pine
+ *      process events.  Normal windows applications are entirly event
+ *      driven.  The top level does nothing but dispatch events.  In
+ *      pine, the top level implements the logic.  Events are only
+ *      dispatched by the lowest levels.
+ *
+ *	In normal applications, mouse down in the scroll bar causes
+ *	an internal scroll function to be entered.  It tracks the
+ *	mouse and issues scroll messages as needed.  If the
+ *	application redraws the screen the scroll function also
+ *	dispatches the WM_PAINT message to the application.  The
+ *	important thing is that this internal scroll function does
+ *	not exit until the mouse is released.
+ *
+ *	We implement two methods for pine's screen managers to deal
+ *	with scroll events.  They can receive scroll events as
+ *	characters in the normal input stream or they can register a
+ *	callback function.
+ *
+ *	In the "insert a character in the queue" mode, the scroll
+ *	event never gets process until the mouse is release.  Auto
+ *	repeat scroll events (generated as the mouse is held down)
+ *	will cause multiple chars to be inserted in the queue, none
+ *	of which will get processed till the mouse is release.  In a
+ *	compromise, we allow only one scroll char in the queue,
+ *	which prevents makes for a more friendly and controllable
+ *	behavior.
+ *
+ *	In the callback mode, the callback repaints the screen, and
+ *	then it calls mswin_flush() which PROCESSES EVENTS!  The
+ *	Windows internal scroll function does NOT expect that.  This
+ *	behavior can confuses the scroll function, causing it to
+ *	miss mouse up events.  We avoid this by setting gScrolling TRUE
+ *	when this routine is entered and FALSE when this routine exits
+ *	All PeekMessage processors avoid processing any message when
+ *	gScrolling is TRUE.

+ * 1.0  Steve Wilhite, 30-Nov-85

+ *      - massive cleanup on code in display.c and search.c
+ *
+ * 2.0  George Jones, 12-Dec-85
+ *      - Ported to Amiga.
+ *
+ * 3.0  Daniel Lawrence, 29-Dec-85
+ *	16-apr-86
