From: Phillip Wood <phillip.wood@dunelm.org.uk>

This allows one to run 'git rebase --exec "make check" --signoff'
which is useful when preparing a patch series for publication and is
more convenient than doing the signoff with another --exec command.
This change also allows --root without --onto to work with --signoff
as well (--root with --onto was already supported). Note that the
failing test is due to a bug in 'rebase --root' when the root commit
is empty which will be fixed in the next commit.
