The commit message is a good chance to quickly explain the API. What
does the function do? When would one call it? Is it equivalent to
running "git rerere clear"? Any gotchas?

Didn't "git rerere" already use the functionality of this function?
I'm not sure what this part means.

This is not a side-effect; you did it directly.
I think the reason for this is that rerere_gc is not being exposed at
the same time, right? I suppose if I were doing it, I would have
moved that to rerere.c, too and kept unlink_rr_item static, but there
is also appeal in a minimal patch. It would be clearer to say
something to the effect that we
Also export unlink_rr_item as unlink_rerere_item so
rerere_clear and the un-libified "git rerere gc" can
both use it.

Why RERERE_NOAUTOUPDATE instead of 0? (Of course it doesn't matter in
practice. Maybe "0" would convey that more clearly?)

The write_lock is never rolled back. "git rerere" won't care since it
exits moments later and the atexit handler is called, but others might
mind that they can't perform any more rerere operations afterwards. :)
Thanks and hope that helps.
