The sleep time is calculated as the sum of all arguments passed.
This makes the FreeBSD version of sleep functionally compatible with

The coreutils version of this command accepts a unit designation of s,
m, h, or d (for seconds, minutes, hours, days) immediately following
the number of (fractional) units to delay.
The submitted patch has been modified in one detail: the test meant to
detect the presence of the unit modified was not specific (!= 1) and
would have accepted a non-numeric initial element or extra characters
following the union. The committed version accepts only the number
immediately followed by one of the defined unit designators and no
further characters.

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.

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.
