Jake GouldingAck - I sent that a bit before I meant to (and before I added patch sequence numbers).
This is a patch that adds a --contains flag to git tag, providing similar functionality as git branch --contains.
Please let me know what else I have inevitably messed up, and I shall endeavor to fix and resubmit.

This functions similar to how --contains works for git branch - it will show all tags that contain the specified commit. Indeed, it uses the same lookup mechanisms as git branch.
