GIT_COMMITTER_* and reflog

It appears the reflog currently allows its log data (name and date) to be overridden by the GIT_COMMITTER_* environment variables. At least for my workflow, this kinda breaks the reflog (as I regularly set GIT_COMMITTER_DATE to produce deterministic commit objects).

Is there a need to support this override for the reflog? Is there any reason it can't be changed to use GIT_REFLOG_* instead?

Note that the reflog does NOT pull the name/date from the commit object itself, but rather calls git_committer_info() to get a new name/date for reflog purposes. So it does not appear to be intentionally designed to use the commit's date.

Thanks for your thoughts,

Luke

P.S. If the reflog date can be made useful like this, maybe I will finish a minor patch to add reflog-date to the pretty formatting format so it can be viewed nicely... ;)
