4750b233ce Prepare POSIX 2013 audit
I can't believe we've come this far! The idea is to look at the
2013 POSIX corrigendum for each tool and deep-test features before
making the first 0.1 release.
To keep the noise low, I'll do this in batches, not on a per-tool-
basis (as many of these are trivial to test).
In the meantime, I'll also think of a fitting STANDARDS section
for the non-POSIX tools. Now that the audits are pretty much done,
I can also have a more relaxed view on standards compliance instead
of having to dig through some uncleaned mess.

To mark this "new beginning", the README has gotten a liftover.
The POSIX 2008-column was more or less useless and as I expect the
checks to go along pretty quickly, I "reset" the compliance state
of all but the non-POSIX tools and will then go along and check every
single one of them in the next few days.

Apart from the few missing flags and audits, sbase should then be
ready to hit the world with the first release after 4 years of work.

49e27c1b0c Add -m and -o flags to sort(1)
Sort comes pretty much automatically, as no script relies on the
undefined behaviour of the input _not_ being sorted, we might as well
sort the sorted input already.
The only downside is memory usage, which can be an issue for large
files.
The o-flag was trivial to implement.

71adaed519 Add s-, t-, x-flags to and audit xargs(1)
The flexible design already allowed to add these flags trivially.
Drop the -I and -L-flags, which are XSI-extensions.
The audit generally consisted of style-changes, dropping kitchen-
sink functions, updating the usage and using estrtonum instead of
strtol.

Nothing special here, only renaming of variables and adding the

587575dcb4 Audit nl(1)
1) Refactor the manpage to use the num-syntax and concise wording.
2) Build format instead of having a list of static strings.
3) BUGFIX: if (!buf[0] || buf[0] == '\n') Process last-read-line
           properly.
4) BUGFIX: In case we hit a formatting line, print a newline instead
           of just dropping it.
5) Use a switch instead of having spaghetti-cases.
6) Don't use printf-magic but explicitly do a putchar(' ')-loop.
7) Update usage(), indent properly.
8) BUGFIX: strchr is not NULL when type[0] is \0. Check for \0
           separately beforehand.
9) Reorder arg.h-cases for better readability.

d49f6f2044 Audit expr(1)
No bugs found, but I changed intmax_t to long long to make it more
predictable and removed some of the kitchen-sinking.
Don't return structs themselves, as this is not very elegant.
Do it like functions like stat(), which take a pointer to a
struct to fill.

b6b977f63d Audit tar(1), add DIRFIRST-flag to recurse()
I've been wanting to do this for a while now, as tar(1) used to
be one of messiest and cruftiest tools.
First off, before walking through the audit, I'll talk about
what the DIRFIRST-flag for recurse() does.
It basically calls fn() on the first-level-dir before calling
it's subentries. It's necessary here, because else the order
of the tar-files would've been wrong (it would try to create
dir/file before creating dir/).

Now, to the audit:
1)  Update manpage, fix mistake that compression is also available
    for compressing. It's only available for extracting.
2)  Define the major, minor and makedev macros from glibc by ourselves.
    No need to rely on them, as they are common sense.

decomp()
3)  Simple refactorization.

putoctal()
4)  Add a truncation check for snprintf().

archive()
5)  BUGFIX: Add checks to any checkable function, don't blindly call
    them, this is harmful and there are 100 ways to exploit that.
6)  Use estrlcpy() instead of snprintf() wherever possible, fix
    alignment.
7)  BUGFIX: Terminate the result-buffer of readlink(), check if
    it even succeeded.
8)  Fix sizeof()-formatting.

unarchive()
9)  BUGFIX: Add checks to any checkable function, don't blindly call
    them, this is harmful and there are 100 ways to exploit that.
10) BUGFIX: strtoul can happily return negative numbers. Add checks
    for that and also if the full string has been processed.
11) Remove calls to perror(). We have eprintf, use it.
12) BUGFIX: "minor = strtoul(h->mode, 0, 8);". We need h->minor of
    course.
13) Fix typo "usupported", remove fprintf-call.

print()
14) Check fread().

xt()
15) Get rid of snprintf-magic. Use estrlcat().
16) BUGFIX: check for ferror() on the tarfile.

usage()
17) Update it. The old usage() was like 1000 years old.

main()
18) Add DIRFIRST-flag to the recursor.
19) Don't print usage() when a mode is re-set. We allow this in
    general.
20) Add function checks and fix error messages.
21) Add tarfilename-global for proper error-messages.

a531865fe5 Audit readlink(1)
1) Properly document e, f and m-flags in the manpage.
2) Clear up the code for the m-flag-handling. Add idiomatic
   '/'-path-traversal as already seen in mkdir(1).
3) Unwrap the SWAP_BUF()-macro.
4) BUGFIX: Actually handle the f-flag properly. Only resolve
   the dirname and append the basename later.
5) Use fputs() instead of printf("%s", ...).

74dcd46c70 Update README in regard to ls(1)
I marked out -m, -s and -x, because they are either visual flags
for interactive mode, which are better solved with tools made for this
job, or superfluous in another sense.
For example, -s basically "steals" the job from du.
In general, some of these options might still be easy to implement.
The options -S and -f are important though, as they are sorting-options
with real use.

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

   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.
