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.

aaac1c8800 Audit tee(1)
1) "duplicate" implies that you can only specify two outputs,
   "multiply" is a better word describing the functionality.
2) fix other wording in the manpage
3) fix usage()
4) reorder local variables
5) fix sizeof() style
6) we need argv later, don't increment argv and rather iterate
   over argc.
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.

1) no need to include sys/stat.h
2) remove the enum which just added a layer too thick on this simple
   program
3) argc-style, other style
4) weprintf instead of enprintf, then save the error-message of
   execvp before and return the proper status.
5) write consistent "not reached" comment.

443de0a859 Add col command
col is used to display troff documents in ttys, removing the reverse
line feeds generated by .2C in ms. This implementation keeps the limit
of 256 lines of 800 characteres of the original implementation.

1) Refactor the manpage, which has been a bloody mess, documenting
   fantasy-flags (-d for example) and add a STANDARDS section
2) fix usage()
3) sort ARG-block
4) Check return-value of stat() separately, so a lack of permissions
   doesn't tell the user "the directory doesn't exist", which could
   be a bit confusing.
5) Add empty line before return.

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
5) Add blank line before return

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
5) Remove bikeshedding-comment. Read the standard if you wonder.
6) return-value trick from env(1)

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.

e7c33c4af3 Audit basename(1)
1) be stricter which number of arguments is accepted (1 or 2)
2) basename already returns a pointer to "." is argv[0] is ""
3) No need to check for *p != '/', because basename() only returns
   a string beginning with '/' which has length 1, so if strlen(p)
   == 1, the only way for suffix to be "evaluated" is for off to
   be > 0, being equal to suffix being "", but "" != "/".
4) don't calculate strlen twice for each string. Store it in a
   ssize_t and check if it's > 0.

44bd931834 Add audit-section to README
Okay, so why another section?
The finished-section applies to general feature-completeness and
manual status. It somehow is not an indicator for general code-
clarity, so the audited-column reflects a thorough audit of the
underlying code and optimization.
Take a look at the upcoming basename(1)-patch for an example on
how this goes.

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.

79e45395e5 Refactor cmp(1) code and manpage
The algorithm had some areas which had potential for improvement.
This should make cmp(1) faster.
There have been changes to behaviour as well:

1) If argv[0] and argv[1] are the same, cmp(1) returns Same.
2) POSIX specifies the format of the difference-message to be:
      "%s %s differ: char %d, line %d\n", file1, file2,
      <byte number>, <line number>
   However, as cmp(1) operates on bytes, not characters, I changed
   it to
      "%s %s differ: byte %d, line %d\n", file1, file2,
      <byte number>, <line number>
   This is one example where the standard just keeps the old format
   for backwards-compatibility. As this is harmful, this change
   makes sense in the sense of consistentcy (and because we take
   the difference of char and byte very seriously in sbase, as
   opposed to GNU coreutils).

The manpage has been annotated, reflecting the second change, and
sections shortened where possible.
Thus I marked cmp(1) as finished in README.
