[PATCH] rebase -i: give rerere a chance

[Johannes Schindelin <Johannes.Schindelin@gmx.de>]

Like non-interactive rebase, interactive mode now calls rerere when
appropriate.

	While I was working with rebase -i yesterday, I realised that it
	did not call rerere at all.  And sure enough, there was a
	NEEDSWORK in rebase -i for that.

	Now, I _hope_ I got all the locations where the rerere should be
	cleared, but this could use a few pairs of eyeballs.
