[PATCH v4 09/15] sequencer: let "git sequencer--helper" callers set "allow_dirty"

[Christian Couder <chriscool@tuxfamily.org>]

This flag can be set when using --reset-hard or --fast-forward, and
in this case changes in the work tree will be kept.

This change is usefull to let people play with the "allow_dirty"
feature.
