This seems like a bad idea. There are already modules it won't work
for, and it won't work for manual commits, for which testing is
probably more important. It would be better to get the paths from git
than scraping it from a commit message. You should already have a
checkout of the super project, so something like this should work:

import subprocess, re

repo_path = '.'
commit = 'HEAD'

raw_diff = subprocess.check_output(['git', '-C', repo_path, 'diff',
commit + '^', commit, '--raw'])
paths = re.findall(r'^:\d{6} 160000 [a-z0-9.]+ [a-z0-9.]+
[A-Z]\t(.*)$', raw_diff, re.M)
print paths
