The correct logic is a lot simpler than the previous iteration. We
record the base fts_name to avoid having to worry about whether we
needed the root symlink name or not (as applicable), then we can simply
shift all of that logic to after path translation to make it less
fragile.
If we're copying to DNE, then we'll have swapped out the NULL root_stat
pointer and then attempted to recurse on it. The previously nonexistent
directory shouldn't exist at all in the new structure, so just back out
from that tree entirely and move on.
The tests have been amended to indicate our expectations better with
subdirectory recursion. If we copy A to A/B, then we expect to copy
everything from A/B/* into A/B/A/B, with exception to the A that we
create in A/B.

As noted in the PR, cp -R has some surprising behavior. Typically, when
you `cp -R foo bar` where both foo and bar exist, foo is cleanly copied
to foo/bar. When you `cp -R foo foo` (where foo clearly exists), cp(1)
goes a little off the rails as it creates foo/foo, then discovers that
and creates foo/foo/foo, so on and so forth, until it eventually fails.
POSIX doesn't seem to disallow this behavior, but it isn't very useful.
GNU cp(1) will detect the recursion and squash it, but emit a message in
the process that it has done so.
This change seemingly follows the GNU behavior, but it currently doesn't
warn about the situation -- the author feels that the final product is
about what one might expect from doing this and thus, doesn't need a
warning. The author doesn't feel strongly about this.

The df command provides a -l option to exclude all non-local file
systems and a -t option with a (positive or negative) list of file
system types to display.
This commit adds support for a combination of -l and -t. If both are
specified, the parameter list of the -t option is applied on top of
the selection of öocal file systems (independently of the order of
the -l and -t options).
E.g., "df -t noprocfs,sysfs -l" will select all local file systems
except those of type procfs and sysfs.

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].

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.

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.
