e37e3e916a Remove file(1) from TODO
We'll probably develop this outside of sbase.  A simple script that
parses /etc/magic and generates magic.h would be sufficient.

The table can be huge and we do not want to bloat up binary size
only for file(1).

ab26b5583e Audit ln(1)
1) Clarify behaviour when the f-flag is given and a target is in its
   own way.
2) Fix usage()-style.
3) Group local variable declarations.
4) reorder args
5) argc style, other boolean style changes
6) improve error messages
7) set argv[argc - 1] to NULL to allow argv-centric loop later
8) BUGFIX: POSIX specifies that when with the f-flag there's a
   situation where a file stands in its own way for linking it
   should be ignored.
9) Add weprintf() where possible, so we don't pussy out when there's
   a small issue. This is sbase ffs!

4) BUGFIX: Probably from the old non-arg.h days, the directory-

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.

8dc92fbd6c Refactor enmasse() and recurse() to reflect depth
The HLP-changes to sbase have been a great addition of functionality,
but they kind of "polluted" the enmasse() and recurse() prototypes.
As this will come in handy in the future, knowing at which "depth"
you are inside a recursing function is an important functionality.

Instead of having a special HLP-flag passed to enmasse, each sub-
function needs to provide it on its own and can calculate results
based on the current depth (for instance, 'H' implies 'P' at
depth > 0).
A special case is recurse(), because it actually depends on the
follow-type. A new flag "recurse_follow" brings consistency into
what used to be spread across different naming conventions (fflag,
HLP_flag, ...).

This also fixes numerous bugs with the behaviour of HLP in the
tools using it.

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) 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.

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.

286df29e7d Make already audited tools argv-centric instead of argc-centric
This has already been suggested by Evan Gates <evan.gates@gmail.com>
and he's totally right about it.
So, what's the problem?
I wrote a testing program asshole.c with

int
main(void)
{
        execl("/path/to/sbase/echo", "echo", "test");
        return 0;
}

and checked the results with glibc and musl. Note that the
sentinel NULL is missing from the end of the argument list.
glibc calculates an argc of 5, musl 4 (instead of 2) and thus
mess up things anyway.
The powerful arg.h also focuses on argv instead of argc as well,
but ignoring argc completely is also the wrong way to go.
Instead, a more idiomatic approach is to check *argv only and
decrement argc on the go.
While at it, I rewrote yes(1) in an argv-centric way as well.

All audited tools have been "fixed" and each following audited
tool will receive the same treatment.
