Subject:    [PATCH JGIT] In the commit dialog, deal with Signed-off-by not on

The previous implementation made the assumption that
the Signed-off-by is always on the last line.

Correct this assumption and deal with Signed-off-by everywhere in
the commit message.

I hope this send will not be whitespace damaged.
