Ok will add.

Ah! this is needed only in branch and tag where we need to see if the options
are used with tag.c and both have a different sort of check for this.
Might need more of a cleanup in branch.c and tag.c before we could do something
like this so that we could have a similar check.

for reference branch.c uses:

    if (!!delete + !!rename + !!new_upstream +
        list + unset_upstream > 1)
        usage_with_options(builtin_branch_usage, options);

whereas tag.c uses what you stated above.
