[PATCH] Documentation: rerere.enabled overrides [ -d rr-cache ]

The wording seems to suggest that you can only globally disable rerere
with the rerere.enabled setting.  But the code actually consults the
config first, and even creates rr-cache for the user if needed.

Noticed while discussing rerere on IRC.  "Can be disabled by setting
this option to false" is of course correct, but insinuates that
setting it to 'true' still falls back to rr-cache, which it doesn't.

git-rerere(1) does not mention the rr-cache fallback; I decided not to
touch it as it's a bit of an implementation detail.  OTOH the
auto-creation of rr-cache can cause strange behavior if a user has
rerere.enabled unset and tries it once, as in

  git config rerere.enabled true
  git merge ...
  git config --unset rerere.enabled
