f14670a1d6 Don't pass '-' to getopt(3). My guess is that *very* old getopt 
didn't handle "--" terminator, so this code was working around it and
not quite correctly at that.

Fixes weird output from

  $ uniq --long-option
  uniq: uniq: No such file or directory

(for more fun, run that command from /usr/bin as root).

Pointed out by Andreas Krey.

77df47bda0 Fix the bug introduced in the previous commit. 
The lengths of the lines being compared were not correct. Essentially, we
were comparing the length of the buffers instead of the length of the strings.

This patch also avoids calling skip() twice for the same line.

Thanks to Rin Okuyama for the patch.

75088523c3 A small optimization: since we already know the length of the lines, check 
if the lenghts are equal before calling strcmp(3). Most of the times, the call
to strcmp(3) can be saved if the lines are not of the same length.

Thanks to Christos for the reviews

c33cd716b3 - improve punctuation; 
- improve wording (explicitly mention the name of the optional
  additional arguments within the text, using macros as well);
- create separate section, and use `.Ex' macro, for exit status
  information;
- bump date.

d4471f4981 Allow -c with -d/-u. While uniq -cu isn't that useful, uniq -cd often is. 
No objection on tech-userlevel, and the arbitrary restriction has been
irritating me for ages.
