[PATCH] Documentation: commit: explain the non-meaning of S-o-b

["Jan Krüger" <jk@jk.gs>]

In the manpage for git commit, the option --signoff is mentioned but
there is no explanation of what it actually means. Add a brief hint that
S-o-b doesn't have a pre-defined meaning.

Signed-off-by: Jan Krüger <jk@jk.gs>

Semi-resend. Nobody commented on this when I first sent it in early
December, so here it is again, with a slightly more verbose
explanation. The repetition is intentional.
