When extracting the patch, we only want the actual patches. We don't want the "---" delimiter. Simplify the extraction by simply deleting everything before the first "diff " line. (Use sed instead of awk to simplify the code.)

Without this patch, "guilt fold" and "guilt push" sometimes fails if guilt.diffstat is true.
