MFC r319836:

2017-07-17T21:19:29+00:00

stat(1): sort flags in the DESCRIPTION section

-x's description should come after -t's description.

2017-07-17T21:01:07+00:00

r319834:

Write up some basic tests for readlink(1)

The tests exercise -f (f_flag), -n (n_flag), and no arguments (basic).

r319841:

Add initial tests for stat(1)

Testcases for -H, -L, and -f haven't been implemented yet, in part due
to additional complexity needed to validate the features:
* -H and -f will require an external "helper" program to display/modify
  the state/permissions for a given path.
* -L is being covered partially via the -n testcase today.

r320723:

Use %e instead of %d with x_output_date(..)

stat -x doesn't 0-fill days so %d is inappropriate. %e is correct.

r320724:

:l_flag:: be more aggressive when normalizing whitespace

Save output from ls -ldT and stat -l, then normalize all repeating whitespace using
sed to single column spaces.

This makes the test flexible with single-digit days, etc, similar to r320723. This
approach is just a bit more of a hammer approach because of how the columns are
ordered/spaced in both ls and stat.

More -Wmissing-variable-declarations fixes.

In addition to adding `static' where possible:

- bin/ed: Move globally used variables into ed.h.
- sbin/camcontrol: Move `verbose' into camcontrol.h and fix shadow warnings.
- usr.bin/calendar: Remove unneeded variables.
- usr.bin/chat: Make `line' local instead of global.
- usr.bin/elfdump: Comment out unneeded function.
- usr.bin/rlogin: Use _Noreturn instead of __dead2.
- usr.bin/tset: Pull `Ospeed' into extern.h.
- usr.sbin/mfiutil: Put global variables in mfiutil.h.
- usr.sbin/pkg: Remove unused `os_corres'.

Synthesize the change from NetBSD's 1.33:

2011-02-11T05:33:35+00:00

"Do not crash if a date cannot be represented (localtime returning
NULL), use the Epoch value instead."

Bring in the relevant changes from NetBSD's 1.31:

2010-12-18T00:30:52+00:00

"Use strlcpy, not strncpy, when the desired semantics are strlcpy's
rather than strncpy's."

Note: NetBSD's 1.32 is their adoption of our r216206

Bring in the change from OpenBSD's 1.14:

2010-12-09T23:57:23+00:00

"synchronize synopsis and usage; "-l", "-r", "-s" and "-x" are mutually
exclusive; while here, slightly improve spacing in the source code
so it fits on a 80-column display again.
