Protect against patches that break the parsing.

A patch that starts with '^From ' in the body
breaks our parsing.

See for example:
https://gitlab.winehq.org/wine/wine/-/merge_requests/307/diffs?commit_id=5fade981ad38ba454191e201ef98f1028b375cfa

This change doesn't make it work perfectly, but keeps
us from failing, and spamming the mailing list.
