[PATCH] git init: activate rerere by default

We have a working implementation of rerere since long ago, and we even
make sure that it works as expected in a test case.  It is also a very
useful feature, so why not turn it on for the benefit of users who are
not even aware of it? This patch does that.

	Maybe it is too late for 1.5.3? But maybe this is nice enough to 
	have in 1.5.3?

	BTW I shamelessly put in a comment to boost my comment ration on 
	ohloh.net...
