I see you don't believe, it, but it really did bootstrap.  As I pointed
out already, it only reproduce on disabled checking bootstrap, while I
did bootstrap with checking enabled (the default settings).  There is
nothing in our commit rules requiring bootstrap with checking disabled.

Usually I do both bootstraps, but it got late yesterday and the patch
was supposed to be bugfix to failure in DLV and the testing machine
crashed and thus I've decided to commit it with only two bootstrap runs
instead of usual four.  It is even mentioned in the email I sent at
commit time.
