[PATCH] Force the medium pretty format on calls to git log

[Pedro Melo <melo@simplicidade.org>]

If a user as set a format.pretty in his config, git-svn rebase will fail with:

Unable to determine upstream SVN information from working tree history

We need to force the medium format to obtain the needed information from the log.
