From: Nguyễn Thái Ngọc Duy <[email protected]>
S-o-b in the middle of a sentence, at the beginning of the sentence
but it is just because of text wrapping, or a full paragraph of valid
S-o-b in the middle of the message. All these are not S-o-b, but
detected as is. Fix them.
[bc: add two additional tests to demonstrate shortcomings of the current
code:
1. failure to detect non-conforming elements in the footer when last
line matches committer's s-o-b.
2. failure to handle various s-o-b -like elements in the footer as
conforming. e.g. "Change-id: IXXXX or Bug: 1234"
