ac62259d24 comm: Print first trailing unpaired line in file 1
Previously, a line read from file 1 before a strcmp was
performed would be overwritten and lost. Something like
this:

    comm one_line_file empty_file

produced no output.

This patch is a bit inelegant, but quite simple.

51390a3c51 Audit sort(1) and mark it as finished
1) Remove the function prototypes. No need for them, as the
   functions are ordered.
2) Add fieldseplen, so the length of the field-separator is not
   calculated nearly each time skipcolumn() is called.
3) rename next_col to skip_to_next_col so the purpose is clear,
   also reorder the conditional accordingly.
4) Put parentheses around certain ternary expressions.
5) BUGFIX: Don't just exit() in check(), but make it return something,
   so we can cleanly fshut() everything.
6) OFF-POSIX: Posix for no apparent reason does not allow more than
   one file when the -c or -C flags are given.
   This can be problematic when you want to check multiple files.
   With the change 5), rewriting check() to return a value, I went
   off-posix after discussing this with Dimitris to just allow
   arbitrary numbers of files. Obviously, this does not break scripts
   and is convenient for everybody who wants to quickly check a big
   amount of files.
   As soon as 1 file is "unsorted", the return value is 1, as expected.
   For convenience reasons, check()'s warning now includes the filename.
7) BUGFIX: Set ret to 2 instead of 1 when the fshut(fp, *argv) fails.
8) BUGFIX: Don't forget to fshut stderr at the end. This would improperly
   return 1 in the following case:
   $ sort -c unsorted_file 2> /dev/full
9) Other style changes, line length, empty line before return.

e153447657 Make sort(1) utf-compliant and update README
Make it clear that <blank> characters just are spaces or tabs and
not a special group which needs special treatment for wide characters.

Also, and that was the only problem here, correctly calculate the
offset given by the key definitions for the start- and end-characters
using libutf-utility-functions.

Mark the progress in the README and put parentheses around the missing
flags which are insane to implement for no real gain.

1622089a21 Reorder functions in sort(1)
I kind of missed that the sorting was still not properly done.
parse_flags() and addkeydef() are independent of everything else,
so they can be put at the bottom.
Sorting the other functions reveals the true hierarchy much better.

e00cdf226a Use queue.h-macros in sort(1)
This is much easier to read than having yet another handrolled

Tested and more or less clearly equivalent.

8d1ae98163 Call C compiler for linking
Using $(LD) directly for linking can cause issues with cross-compilers
and various other toolchains, as various libraries such as libc may not
be implicitly linked in, causing symbol resolution errors.
Linking through the C compiler frontend solves this issue.

d848bcac4b Fix parameter-usage in printf(1)
1) Don't default to a space for numeric conversions. Instead,
   set flag to 0 and work with it on a case-basis.
   This fixes the wrong output of "printf %d 20" which had a
   space prepended to it (" 20").
2) Add precision for doiuxX, which is zero-padding.
   This fixes the wrong output of "printf %.5d 20" to properly
   print "00020".

Thanks to emg for reporting these!

78b285deb6 Fix ln(1) symbolic link handling
This was broken in multiple ways. For instance, the overlay-
check of identical files (name and target) was omitted for
symbolic links for some reason.
While at it, I fixed the stat-handling, improved the error-
messages so the right paths were shown and removed the
illegimite bail-out when the target-fstatat failed (we want
only a warning here as well).

Get rid of the !!()-constructs and use ret where available (or introduce it).

In some cases, there would be an "abort" on the first fshut-error, but we want
to close all files and report all warnings and then quit, not just the warning
for the first file.

1797df01e7 Fix uniq(1)
The argument handling was quite garbled up. So I fixed it.
In the process, it drops a lot of locs.

Previously, it would lead to an off-by-one in an edge case, so
stop messing around with argv and use an idiomatic fp- and fname-
array.

Now this works fine and is much easier to read.

This is also the first step towards going back to strcmp() instead
of handrolling the "-"-checks.

1d28fbd6cf mv, cp: Preserve nanosecond timestamps
Otherwise, we run into problems in a typical autoconf-based build
system:

  - config.status is created at some point between two seconds.
  - config.status is run, generating Makefile by first writing to a file
    in /tmp, and then mv-ing it to Makefile.
  - If this mv happens before the beginning of the next second, Makefile
    will be created with the same tv_sec as config.status, but with
    tv_nsec = 0.
  - When make runs, it sees that Makefile is older than config.status,
    and re-runs config.status to generate Makefile.

0545d32ce9 Handle '-' consistently
In general, POSIX does not define /dev/std{in, out, err} because it
does not want to depend on the dev-filesystem.
For utilities, it thus introduced the '-'-keyword to denote standard
input (and output in some cases) and the programs have to deal with
it accordingly.

Sadly, the design of many tools doesn't allow strict shell-redirections
and many scripts don't even use this feature when possible.

Thus, we made the decision to implement it consistently across all
tools where it makes sense (namely those which read files).

Along the way, I spotted some behavioural bugs in libutil/crypt.c and
others where it was forgotten to fshut the files after use.
