True, but it will be later be reset to 2012 when you run
"./configure && make && make dist", so no big deal.

Though, we might be even nicer, and make bootstrap.sh pre-processed
by "make update-copyright" so that the value of $RELEASE_YEAR will
always be correct, even in the bootstrap phase.  This is what I've
done with the attached patch (pushed to maint).
