We should first speed up the general "--verify $ref" case; as you corrected me earlier it still has a useless loop. If it is still too slow (which I suspect it could be the case, with fork+exec overhead), we should _also_ pursue the filter approach, but even then I think "filter out the valid ones" is a specialized hack, if you mean "show only the invalid one's names" by --show-invalid. It would make sense to do $ git show-ref --show-invalid v1.0.0 v2.6.18 f665776185ad074b236c00751d666da7d1977dbe refs/tags/v1.0.0 - refs/tags/v2.6.18 (and its equivalent to take refs from --stdin) though.
