Please keep Jonathan Cc:-ed, he's been very helpful with this series

This series is mostly alright by me, a few minor comments inline.

Didn't we agree to use done_testing()?   Perhaps (as you suggested) with
a private copy of Test::More?  It's probably easier to start using
done_testing() earlier rather than later.

For new code related to git-svn, please match the existing indentation
style (tabs) prevalent in git-svn.  Most of the Perl found in git also
uses tabs for indentation.
