[Tracker-discuss] [issue415] Mercurial integration: regression in diff generation

“utterly broken” is a very strong opinion.  The git diff format supports things that unified diff does not and has one drawback to my knowledge (I forgot exactly what—it was one missing piece of information that you mentioned during one of the python-dev threads about Mercurial migration or Roundup-Mercurial integration).  Everyone recommends always using git diffs.

I’m sorry I don’t know exactly.  I have this comment from the bug report:

> I'm not sure how the bugtracker patch mechanism works, but the patch it produced included a lot of changes > that I didn't make (changesets already committed to the master repo).
