- Use Cm instead of Ar or Sq for command modifiers of the -v flag.
- Remove unnecessary "Ar ..." from the synopsis. It's not clear what it
was referring to.
- Add missing arguments to the -f and -v flags.
- Stylize the dot before "ss" with Cm in the default format in the -f
flag description.
- Set LC_ALL=C in the last example so that the output format of
date(1) always matches the specified format of the -f flag not matter
the locale.
- List the -f flag as optional in all usage lines in the synopsis.

When there are many matches, find the longest common substring starting
from the beginning of each command and use that to replace input.
As an example: on my system, llv<tab> will be autocompleted to llvm-
and another <tab> will print all matching llvm commands.

Until this change, any bindings set in histedit() were lost on calls to
bindcmd().
Only bind -e and bind -v call libedit's keymacro_reset(). Currently you
cannot fool libedit/map.c:map_bind() by trying something like bind -le
as when p[0] == '-', it does a switch statement on p[1].
(cherry picked from commit 9413dfd331)
When multiple matches are found, we keep the provided string on the
input line and print unique matches as suggestions.
But the multiple matches might be the same command found in different
directories, so we should deduplicate the matches first and then decide
whether to autocomplete the command or not, based on the number of
unique matches.

(cherry picked from commit 5ff2e55e00)
The following situation can trigger the deadlock:
1) Long time ago a_service was started through rc.d
2) We want to restart a_service and issue service a_service restart
3) rc.subr reads current process PID (via file or process),
sends TERM signal and runs pwait with PID harvested
4) a_service process dies very quickly so it's PID becomes available.
It is possible that while original process was running,
PID counter overflowed and pwait got assigned a_service's PID.
This patch ignores pid(s) to wait that are equal to pwait PID.

There is no guarantee that after close(2)/free the errno will remain

PR252358 reported a serious performance problem when
copying a large non-sparse file on a UFS file system.
This problem seems to have been caused by a large
number of SEEK_HOLE operations, with one done
for each copy_file_range(2) call.
This patch modifies cp(1) to use a large (SSIZE_MAX)
len argument, reducing the number of system calls
and resolving the performance issue.
While here, convert the type of the "rcount" from "int"
to "ssize_t" so that it is consistent with that returned
by both read(2) and copy_file_range(2).

This change has been motivated by a mail from bde sent in 2015 in
which he mentioned inappropriate use of sscanf() in 3 programs in
/bin.
This change removes the potential mismatch of the types of the return
values and the variable width specified in the scan pattern. While
there was no issue with the patterns and types used, the new code is
simpler and more efficient.
The previous version normalized the width list (replaced empty fields
with "0") just to be able to use sscanf() on the string.
It is much simpler to just parse the string as-is.
The clearing of f_notabs is preserved for the case that less than 9
width values have been defined, but I do not understand the rationale
for this particular condition. E.g., LS_COLWIDTHS="::::::::" will be
counted as 9 defined fields (may clear f_notabs) but is no different
fron LS_COLWIDTHS="" with regard to the field width (and that does not
clear f_notabs, since there are less than 9 fields).
This is addressing cases such as fts_read(3) encountering an [EIO]
from fchdir(2) when FTS_NOCHDIR is not set. That would otherwise be
seen as a successful traversal in some of these cases while silently
discarding expected work.
As noted in r264201, fts_read() does not set errno to 0 on a successful
EOF so it needs to be set before calling it. Otherwise we might see
a random error from one of the iterations.
gzip is ignoring most errors and could be improved separately.

The acl_from_stat function accepts a stat_t * argument, but only uses its
st_mode field. There is no reason to pass the whole struct, so make it accept
a mode_t and rename the function to acl_from_mode.
Linux has non-standard acl_from_mode function in its libacl, so naming the
function this way may help discovering it during porting efforts.
