Would it be possible to add an option to git-describe that limits the candidate tags to those matching a glob pattern or regular expression? I've got a repository imported from CVS which has a number of less interesting tags for events such as branch creation, but I'm only interested in describing the current commit relative to tags matching v[0-9]\.[0-9]*, rather than the closest tag of any spelling.

Sure, it shouldn't be too difficult, just need to alter the get_name() function to add the item with add_to_known_names() only if it matches the pattern. Take a look at builtin-describe.c around line 74...

We only match things that were "added". So if you don't add a tag via add_to_known_names() then git-describe won't return it.

However that's only true for the standard case; for --contains its a different story as we are actually passing everything to name-rev.

A good news is that name-rev is supposed to respect the name limiter.
