When listing a directory containing dangling symlinks,
and not outputting a long format listing, and orphaned links
are set to no coloring in LS_COLORS, then the symlinks
would get no color rather than reverting to the standard
symlink color. The issue was introduced in v8.13-19-g84457c4
* src/ls.c (print_color_indicator): Use the standard method
to check if coloring is specified for orphaned symlinks.
The existing method would consider 'or=00' or 'or=0' as significant
in LS_COLORS. Even 'or=' was significant as in that case the
string='or=' and the length=0. Also apply the same change
for missing symlinks for consistency.
(gobble_file): Remove the simulation of linkok, which is only
tested in print_color_indicator() which now handles this directly
by keying on the LS_COLORS values correctly.
* tests/misc/ls-misc.pl: Add a test case.
* THANKS: Add the reporter.
* NEWS: Mention the fix.

Handle non-negative whole numbers robustly and efficiently when
the increment is 1 and when no format-changing option is specified.
On the correctness front, for very large numbers, seq now works fine:
$ b=1000000000000000000000000000
$ src/seq ${b}09 ${b}11
100000000000000000000000000009
100000000000000000000000000010
100000000000000000000000000011
while the old one would infloop, printing garbage:
$ seq ${b}09 ${b}11 | head -2
99999999999999999997315645440
99999999999999999997315645440
The new code is much more efficient, too:
Old vs new: 55.81s vs 0.82s
$ env time --f=%e seq $((10**8)) > /dev/null
55.81
$ env time --f=%e src/seq $((10**8)) > /dev/null
0.82

These commands would evoke an invalid diagnostic:
$ mkdir d && ln -s d s && env rm -r s/
rm: cannot remove 's': Too many levels of symbolic links
remove.c was stripping trailing slashes from "s/" before passing
the name to "rm". But a trailing slash may change the semantics,

Before this change, a directory cycle induced by a bind mount

sort -u could omit one or more lines of expected output.
This bug arose because sort recorded the most recently printed line via
reference, and if you were unlucky, the storage for that line would be
reused (overwritten) as additional input was read into memory. If you
were doubly unlucky, the new value of the "saved" line would not only
match the very next line, but if that next line were also the first in
a series of identical, not-yet-printed lines, then the corrupted "saved"
line value would result in the omission of all matching lines.
* src/sort.c (saved_line): New static/global, renamed and moved from...
(write_unique): ...here. Old name was "saved", which was too generic
for its new role as file-scoped global.
(fillbuf): With --unique, when we're about to read into a buffer that
overlaps the saved "preceding" line (saved_line), copy the line's .text

When the combination of the file system options with given files or
devices does not lead to output, "df --total" would exit successfully
although it should not.
Examples:
$ df --total --type=xfs / # when / is not an XFS file system
$ df --total --local -t nfs DIR # nfs is remote per se ...
$ df --total -t qwerty /dev/sdb5 # typo in file system type
Furthermore, "df --total" would not print the error message "no file
systems processed" when the file argument does not exist or is otherwise
not accessible.
Example:
$ df --total __not_exist__
These 2 bugs are present since --total was added by commit
v6.12-166-gea2887b.
* src/df.c (get_dev): Do not set file_systems_processed to true when
force_fsu is true, i.e. when the row for the "total" line is processed.

It's awkward to read and problematic for scripts when
control characters like '\n' are output.
Note other fields are already handled with mbsalign,
which converts non printable chars to the replacement char.
A caveat to note with that, is the replacement char takes
a place in the field and so possibly truncates the field
if it was the widest field in the records.
Note a more general replacement function, that
handles all printable, or non white space characters,
would require more sophisticated support for various
encodings, and the complexity vs benefit was not
deemed beneficial enough at present.
Perhaps in future a more general replacement function
could be shared between the various utilities.
Note <space> is unaffected in any field,
which could impact scripts processing the output.
However any of the number fields at least could have
spaces considering `LANG=fr_FR df -B\'1`, so it's
probably best to leave spaces, which also allows
scripts to handle mount points with spaces without change.

struct statfs has the f_frsize member since Linux 2.6,
so use that rather than f_bsize which can be different.
Note the related df change mentioned in NEWS is handled
in gnulib by using statvfs() rather than statfs()
on Linux > 2.6.36 (where statvfs doesn't hang) and the
same method as stat for Linux 2.6 kernels earlier than that.
stat(1) doesn't use statvfs() on GNU/Linux as the f_type
member isn't available there.
Note the change to not use statvfs() on GNU/Linux was introduced
in gnulib commit eda39b8 16-08-2003.

In order for ls --color to color each symlink, it must form the name
of each referent and then stat it to see if the link is dangling, to
a directory, to a file, etc. When the symlink is to a relative name,
ls must concatenate the starting directory name and that relative name.
When, in addition, the starting directory was "/" or "/some-name",
the result was ill-formed, and the subsequent stat would usually fail,
making the caller color it as a dangling symlink.

... i.e., don't use the getpw* functions.
Before this change, running groups or id with no user name argument
would include a group name or ID from /etc/passwd. Thus, under unusual
circumstances (default group is changed, but has not taken effect for a
given session), those programs could print a name or ID that is neither
real nor effective.
To demonstrate, run this:
echo 'for i in 1 2; do id -G; sleep 1.5; done' \
|su -s /bin/sh ftp - &
sleep 1; perl -pi -e 's/^(ftp:x:\d+):(\d+)/$1:9876/' /etc/passwd
Those id -G commands printed the following:
