test-command-template.t: fix test so it all year This test started failing for me after midnight UTC on December 31st. Fixed it by specifying a date 7 years in the future more precisely (rather than just adding 8 to the year and specifying January 1st), which allows the test to pass both now and on 2012-12-01 at the same time.

amend: prevent loss of bookmark on failed amend The active bookmark were moved to the temporary commit. When the transaction were rollbacked, the bookmark were lost. We now temporarly disable the bookmark to prevent this effect.

amend: invalidate dirstate in case of failure (issue3670) The temporary commit created by amend update the dirstate. If the final commit fails, we need to invalidate the change made to the dirstate, otherwise the release of the wlock will write the dirstate created after the rollbacked temporary commit. This dirstate writing logic should probably be handled in the same object than the transaction one. However such change are too big for stable.
