In this case, we are checking for copies. Perhaps there is a reason
why we want to include relevant_sources in that case, so I'll look
for it later.

This seems backwards from your cover letter. You are using the exact renames
_and_ basename matches to remove the unneeded paths. Why are we not stripping
out the relevant_sources in the call further up, before we call
find_basename_matches()?
