Running refresh internally in runstatus without writing the result out _might_ be an option, but that would largely be a hack to only help qgit.

Other shapes of "git status", such as "git status <filename>" and "git status -a", still need to perform the same index manipulation as "git commit" with the same parameters before calling git-runstatus, and at that point the extra "internal refresh" in runstatus is an unwelcome extra cycle.
