- 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.

Patch from Bug Hunting.

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.

Don't limit lines to 8K.

Bump date for previous.

Note that uniq uses a max line length of 8192 bytes.

Move UCB-licensed code from 4-clause to 3-clause licence.

Generate <>& symbolically. I'm avoiding .../dist/... directories for now.

WARNSify, fix .Nm usage, deprecate register, getopt returns -1, use <err.h>

Minor tweaks: including header files to bring prototypes into scope,
explicitly declaring function return values, etc. to make gcc -Wall
shut up.

Add RCS indentifiers.

remove unused label

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).

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
