[PATCH v2 0/2] Two cleanups around 'prefetch' refs

Here are a couple things that caught my eye during a recent evaluation of
the maintenance feature:

 1. 'refs/prefetch/' refs show up in 'git log' decorations. Auto-hide these.
 2. t7900-maintenance.sh had some scary warnings that end up being
    unimportant.

This is based on 'master' at 66e871b (The third batch, 2021-01-15).

Update in v2: deleting refs more safely for alternate ref backends. (Thanks,
Taylor!)

Thanks, -Stolee
