1bc002b44a Audit paste(1)
Well, basically there was not a lot to do, as I already (fortunately)
audited this code a while back.
There were only minor style-changes.

683d108387 Audit logname(1)
1) Add usage().
2) Idiomatic argv0-setter. We don't use arg.h, as we do not process
   flags or arguments.
3) Remove program-name from eprintf-call. This is done in the eprintf-
   function itself when the DEBUG-define is set.
   We'll activate it by default later.
4) Add empty line before return.

1) Refactor the manpage with num-options, optimize wording to be more
   concise and to the point, pid also specifies process groups.
2) Make int sig const.
3) Remove prototypes.
4) /* not reached */ consistency.
5) Refactor usage() with eprintf.
6) Refactor arg-parser with a switch, use estrtonum
7) Use return instead of exit() in main()
8) argc-argv-correctness.

695153ac18 Audit cmp(1)
1) Remove the return-value-enum, which is not necessary for a simple
   program like this.
2) Don't disallow both l and s to be specified. This is undefined
   behaviour defined by POSIX, so we don't start demanding things
   from the user.
3) Replace exit() with return (we are in main).
4) Refactor main loop to never return in the loop, but actually
   set the same-value and break, which increases readability.
5) Remove the final fclose()'s. The OS will take care of them, no
   need to become cleansy here.
6) Use idiomatic return-value using same. This concludes the
   increase of readability in the main-loop.

109f6b5a60 Audit mv(1)
1) Make argument-naming consistent with other tools (cp(1), ...)
2) style fixes
3) usage() fix
4) BUGFIX: Probably from the old non-arg.h days, the directory-
   check was only done when argc > 3, but with arg.h, this ignores
   the case when 3 arguments were given.
   This is actually a pretty serious issue and I'm glad it's fixed.
5) Moreover, be more verbose when stat() fails and make it clearer
   what the hell is going on at this checkpoint.

   "multiply" is a better word describing the functionality.
2) fix other wording in the manpage

4) reorder local variables
5) fix sizeof() style
6) we need argv later, don't increment argv and rather iterate

7) Improve error messages, print the filename which the write
   failed to instead of printing the buffer itself (how much
   sense does that make, printing 1024 Bytes of garbage?).
   Also, give the name of the function which failed.

520d87e58e Audit mkfifo(1)
1) Fix usage()
2) Group local variables
3) Idiomatic argv-loop
4) BUGFIX: When the m-flag is specified, POSIX clearly says:
   "Set the file permission bits of the newly-created FIFO to the specified mode
   value."
   This means, that if mkfifo() fails for some reason, it should not try to
   chmod() the given path (which has been fixed with the "else if")
   A simple testcase is:

   $ touch testfile; mkfifo -m 000 testfile;

   GNU mkfifo(1): ls -l testfile
   -rw-r--r-- 1 testfile

   sbase mkfifo(1): ls -l testfile
   ---------- 1 testfile

c01641c897 Audit nice(1)
1) val is sufficient as "int" (read the standard)
2) BUGFIX: If getpriority fails, it returns -1 and sets errno.
   Previously, it would correctly catch the errno but not take
   care of the fact that by then val has been decremented by 1.
   Only change val if the getpriority-call has been successful.
3) Add LIMIT()-macro from st to increase readability.
4) setpriority returns < 0 on failure

6c3ba4c4c7 Audit rmdir(1)
1) style fix (don't arrange local variables)
2) BUGFIX: Previously, if ret was turned 1 for some folder, it
   would disable the p-flag for every following folders, which
   is not desired.
   Instead, the "else if" makes sure that the p-flag-section is
   only entered when the initial rmdir succeeds.
3) BUGFIX: Previously, the program would cancel with eprintf if
   it failed to remove one folder in the parent-pathname.
   This is not desired, as we have other folders pending.
   Instead, print a warning for the current failing parent-folder,
   set ret to 1 and break off the loop at this point.
   This allows to finish the other pending folders without issues.

e5b5497773 Add UTF-8-support to strings(1), add t-flag and refactor code
Previously, the string-length was limited to BUFSIZ, which is an
obvious deficiency.
Now the buffer only needs to be as long as the user specifies the
minimal string length.
I added UTF-8-support, because that's how POSIX wants it and there
are cases where you need this. It doesn't add ELF-barf compared to
the previous implementation.
The t-flag is also pretty important for POSIX-compliance, so I added
it.
The only trouble previously was the a-flag, but given that POSIX
leaves undefined what the a-flag actually does, we set it as default
and don't care about parsing ELF-headers, which has already
turned out to be a security issue in GNU coreutils[0].

bafd41e1cf Add printf(1)
This is a particularly interesting program.
I managed to implement everything according to POSIX except how
octal escapes are specified in the standard, which is yet another
format compared to the one demanded for tr(1).
This not only confuses people, it also adds unnecessary cruft
for no real gain.
So in order to be able to use unescape() easily and for consistency,
I used our initial format \o[oo] instead of \0[ooo].

Marked as optional is UTF-8 support for %c in the POSIX specification.
Given how well-developed libutf has become, doing this here was more
or less trivial, putting us yet again ahead of the competition.
