[PATCH 2/3] log: --date and --no-date to toggle reflog dates

[Thomas Rast <trast@student.ethz.ch>]

Introduce two new options that help the user, especially in the case
where log.date is set to some value other than "normal":

--date: equivalent to --date=normal if it was previously "default"
--no-date: equivalent to --date=default

This means that 'git reflog --date' will always show reflog entries by
date, and 'git reflog --no-date' won't even if log.date is set.

 `--date=default` is like `normal`, except for reflog entries where the
 entry number is shown instead.
