Nit: stylistically, we'd put the multiline string literal inside parens to make
it  a bit clearer that the strings should be treated as one an concatenated,
i.e.:

RunGit(['commit', '-m', ('...'
                         '...'
                         % { .. })])

Done.

     cl = Changelist()
     cl.SetIssue(issue)
     cl.SetPatchset(patchset)
