[PATCH 2/2] git-runstatus --refresh

[Junio C Hamano <junkio@cox.net>]

This teaches git-runstatus a new option --refresh to refresh the
index in-core.

 * If a cache has 20k+ paths, this could be rather expensive
   because git-status already have refreshed the entries for us,
   so I am reluctant to make this the default, but obviously
   then qgit needs to know if it has runstatus that knows about
   this option.
