[PATCH] tag: Use OPT_BOOL instead of OPT_BOOLEAN to allow one action multiple times

[Stefan Beller <stefanbeller@googlemail.com>]

As of b04ba2bb (parse-options: deprecate OPT_BOOLEAN, 2011-09-27),
the OPT_BOOLEAN was deprecated.
While I am going to replace the OPT_BOOLEAN by the proposed OPT_BOOL or
the OPT_COUNTUP to keep existing behavior, this commit is actually a
bug fix!

In line 499 we have:
	if (list + delete + verify > 1)
		usage_with_options(git_tag_usage, options);
Now if we give one of the options twice, we'll get the usage information.
(i.e. 'git tag --verify --verify <tagname>' and
'git --delete --delete <tagname>' yield usage information and do not
do the intended command.)

This could have been fixed by rewriting the line to
	if (!!list + !!delete + !!verify > 1)
		usage_with_options(git_tag_usage, options);
or as it happened in this patch by having the parameters not
counting up for each occurrence, but the OPT_BOOL just setting the
variables to either 0 if the option is not given or 1 if the option is
given multiple times.

However we could discuss if the negated options do make sense here, or if
we don't want to allow them here, as this seems valid (before and after
this patch):
	git tag --no-verify --delete <tagname>
