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.

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.

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

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
