From: Phillip Wood <phillip.w...@dunelm.org.uk>
Allow --signoff to be used with --interactive and --merge. In
interactive mode only commits marked to be picked, edited or reworded
will be signed off.
The main motivation for this patch was to allow 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).
Signed-off-by: Phillip Wood <phillip.w...@dunelm.org.uk>

Notes:
changes since v1:
- added support for --signoff with --interactive and --merge
- split out the --preserve-merges test into the next commit
- updated the documentation for --signoff
- reworded commit message to reflect above changes
