These two configuration variables are described in the documentation
to take an expiry period expressed in the number of days:
gc.rerereResolved::
Records of conflicted merge you resolved earlier are
kept for this many days when 'git rerere gc' is run.
The default is 60 days.
gc.rerereUnresolved::
Records of conflicted merge you have not resolved are
kept for this many days when 'git rerere gc' is run.
The default is 15 days.
There is no strong reason not to allow a more general "approxidate"
expiry specification, e.g. "5.days.ago", or "never".
Tweak the config_get_expiry() helper introduced in the previous step
to use date.c::parse_expiry_date() to do so.
In the future, we may find other variables that only allow an
integer that specifies "this many days" (or other unit of time) and
allow them to also do the same, and at that point we probably would
want to move the helper to a place that is not specific to the
rerere machinery. Perhaps config.c would be such a good neutral
place, as it will allow git_parse_signed() to go back to static to
the file.
But this will do for now.
