Fix basement detection for empty commit message bodies

The get_body_parts() method added in ba6c790 (Parse body parts into
usual chunks, 2020-04-27) splits the commit message body on "\n---\n"
and takes the second half as the "basement" of the patch.  The body is
stripped of flanking new lines, though, so a delimiter beginning with
a new line isn't appropriate for commit messages without a message
body.  Make the starting new line optional.

Note that this doesn't matter in the end in terms of the final applied
patch.  Before 31f33fd (Fix body part parsing when '---' is not used,
2020-06-08), the expected patch output was produced despite the diff
lines being processed as the message body.  After that commit, the
information following the triple dash is a bit off, but it doesn't
matter because git discards it anyway.
