You just reported this $tag needs quoting ;-).

You are saying:
	if "$tagid" is already commit then continue;
        if "$tagid" dereferences to a commit and if you have it
	then continue

If that is the case, then this might be more efficient.

	GIT_DIR=../.. git-rev-parse --verify "$tagid^0" >/dev/null 2>&1 && continue

You can say ^{commit} instead of ^0 if you like that newer style, of course.
