[PATCH] cg-fetch: handle tags with funny chars, retrieve missing commits

 + handles tags with funny chars a bit better
 + will check tagrefs, trying to ensure it actually has the relevant
   commits. If the commits are missing, it'll go out and fetch them.
 + if the tagref points to a blob and we have it, it'll skip it

This isn't a complete solution for cg-fetch -- git-fetch is actually
much smarter now, and cg-fetch should perhaps be a thin wrapper
around it, dropping all the duplicate code.

This version uses ^0 instead of ^{commit} which does a more thorough check,
so we don't need to call git-cat-file.
