What's the recommendation for forgetting all rerere's records?

Hi all,

When outside the context of a conflict (no rebase/merge in progress),
what's the intended workflow to clear out the contents of
$GIT_DIR/rr-cache?

We have developers who'd like to discard their faulty resolutions after
completing a rebase gone awry (but not aborted). There doesn't seem to
be a recommendation in git-rerere(1) for how to deal with this
situation. (git-rerere-forget seems to only work in the context of an
active conflict -- and is documented as such.)

I'm wary of recommending `rm -rf "$(git rev-parse --git-dir)/rr-cache"`
-- it's hard to describe this as anything but hacky when the rest of the
experience is handled in porcelain.

Thanks!
