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.

274e86e1aa Audit cp(1)
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.

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.

3) Stop the naïve usage of "/dev/fd/0" and use plain stdin

Now that -c behaves correctly, the tools are pretty much done.

specify the c-flag.

9b06720f62 Refactor cryptcheck() to allow multiple list-files and stdin
Previously, it was not possible to use

sha1sum test.c | sha1sum -c

because the program would not differenciate between an empty
argument and a non-specified argument.
Moreover, why not allow this?

sha1sum -c hashlist1 hashlist2

Digging deeper I found that using function pointers and a
modification in the crypt-backend might simplify the program
a lot by passing the argument-list to both cryptmain and
cryptcheck.
Allowing more than one list-file to be specified is also
consistent with what the other implementations support,
so we not only have simpler code, we also do not silently
break if there's a script around passing multiple files to
check.

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.
