I'm not sure how easy this is going to be. It looks like the patch is applied with
'git --apply' from the file stgit/git.py:apply_patch(). The default '-p' value is 1,
so we'd have to figure out how to pass the 0 along and then get it into the
apply_patch() function.

Zowie, I thought I only had to worry about folks sending patches with incomplete
information. So you get patches to the ada compiler that are rooted in gcc/ada (e.g.
patch in tarball says "./ChangeLog", instead of gcc/ada/ChangeLog) rather than at a
top level? Only way I could see to deal with that would be to try and pass in the
appropriate prefix from the command line.

My current plans are to clean up the first cut at the tarfile logic, then write a
test to keep Karl happy, then try to come up with a way to deal with importing
patches that don't have complete email addresses, no descriptions, etc. Once I get
through that, I'll see if we can deal with weirdly rooted patch series.
