This line doesn't belong in a commit message; it's fine to put it after
the --- separator though, if it aids mailing list reviewers.

Please wrap your commit message lines.  Since 'git log' displays logs
with indentation, wrapping around 72 characters is ideal.

These are not valid S-o-b, therefore this patch cannot be applied as-is.

This is not a valid patch.  Are you replying to a patch that someone
else posted? If so, your quoting style is VERY difficult to read.
Please consider using a leading > before every line that you are quoting
(rather than pasting it verbatim as if you had written it), and include
a blank line both before and after every line that you insert, to call
visual attention to what is your reply vs. what you are quoting.
