(usage): Document only the intersection of the old and new behaviors,
to encourage portability.
(short_options): Remove; no longer needed.
(COMMON_SHORT_OPTIONS): New macro.
(SEP_STRING_OPTION): Remove; no longer needed.
All uses changed to back to the corresponding short options.
(main): Parse options using POSIX 1003.1-2001 rules if
conforming to that standard. Do not warn of obsolete options.

support of obsolete "-N" option syntax in expand, head, fold,
split, tail, unexpand, uniq, and which prohibits options with
optional arguments in od and pr.
(usage): Document it.
(main): Check for obsolete options.
(short_options): New constant.
(SEP_STRING_OPTION): New enum value.
(long_options): Use it.

HELP_OPTION_DESCRIPTION and VERSION_OPTION_DESCRIPTION.

instead of hard-coding --help and --version descriptions.
|
|
|
|
Split usage strings so that --help and --version descriptions are alone
in their own string.
Likewise for the one that says:
Mandatory arguments to long options are mandatory for short options too.
|
|
(struct COLUMN) [char_func]: Declare as a protype.
|
|
Use fputs, not printf.

(standard_header, header, test_suite): Remove.
(date_format, date_text, file_text, header_width_available): New vars.
(long_options, main, init_header, usage):
Add new -D or --date-format option.
(CHARS_FOR_DATE_AND_PAGE, T_BUF_FMT, T_BUF_SIZE, NO_DATE): Remove.
(init_header): Allow arbitrary width for date format. Change
"Page %5d" to "Page %d", since the code no longer assumes fixed width.
Do not assume that localtime succeeds.
(init_header, print_header, usage): Do not truncate headers.
(init_header, print_header): Defer width calculations until
page is printed, since "Page 100000" is wider than "Page 1".
Count columns, not bytes, in page headers.
Custom headers take up only the center, not the whole header.
(print_header): Use printf rather than fprintf(stdout).

Handle the case correctly when digits options immediately precede a
non-option.

Allocated buffer was sometimes too small.

bounded-pointers-enabled gcc).
(init_header): Move declarations of several variables into the
inner scope where they are used.

only 2. The strings had grown to be longer than 2048, which evokes
errors when compiling with Irix4's cc.

* src/pr.c
(main): Redefine options -s, -w to be POSIX compliant; introduce
new options -J, -S, -W to disentangle -s and -w when used together
with the three column options;
(add_line_number): Make POSIX compliant; use default number
separator TAB with single column output.
(add_line_number): Make POSIX compliant; with multicolumn output
now prefer `text columns of equal width' rather than a consequent
use of `default n-separator TAB'.
(add_line_number): Change line number cut-off from lower-oder to
higher-oder digit to avoid loss of information; no consequent
handling exists in different utilities and other UNIXes.
(char_to_clump): Expand input text tabs to 8 spaces, if
input_tab_char doesn't equal TAB (adapted to other UNIXes).
(usage): Update POSIX compliant options -s, -w; add new options -J,
-S, -W.
(main): Update the source internal documentation.
Some smaller BUGFIXES (print_sep_string, init_header, skip_to_page,
reset_status, print_header).
|
|
[long_options]: Remove the "help" and "version" entries.
Remove declarations of show_help and show_version.
(main): Use parse_long_options, including author name(s).
Remove the show_version and show_help blocks.

Remove definitions of those symbols.
* src/csplit.c: Move inclusion of regex.h/rx.h to follow system.h
since it now includes limit.h which defines RE_DUP_MAX.
* src/nl.c: Likewise.
* src/tac.c: Likewise.
