Re: [PATCH] Make builtin-tag.c use parse_options.

Also, this removes those tests ensuring that repeated
-m options don't allocate memory more than once, because now
this is done after parsing options, using the last one
when more are given. The same for -F.

The reason for this change is...?  Is this because it is
cumbersome to detect and refuse multiple -m options using the
parseopt API?  If so, the API may be what needs to be fixed.
Taking the last one and discarding earlier ones feels to me an
arbitrary choice.

While I freely admit that I do not particularly find the "One -m
introduces one new line, concatenated to form the final
paragraph" handling of multiple -m options done by git-commit
nice nor useful, I suspect that it would make more sense to make
git-tag and git-commit handle multiple -m option consistently,
if you are going to change the existing semantics.  Since some
people really seem to like multiple -m handling of git-commit,
the avenue of the least resistance for better consistency would
be to accept and concatenate (with LF in between) multiple -m
options.

With multiple -F, I think erroring out would be the sensible
thing to do, but some people might prefer concatenation.  I do
not care either way as long as commit and tag behave
consistently.
