[RFC/PATCH] bisect: clean flags after checking merge bases

[Junio C Hamano <gitster@pobox.com>]

Unless there is a good reason to belieave that a particular
invocation of a get_merge_bases*() is the last one that cares about
the object flags the computation of merge bases leaves on the
objects, the "cleanup" parameter should always be true, and I do not
think there is one in this codepath.

Found by code inspection.

 * I am planning to eventually change the function signature for
   this function to drop "cleanup" and change rare selected
   codepaths that know what they are doing to call a separate
   function that allows the flags not to be cleaned up.  Two calls
   in builtin/merge-base.c are both the last ones that can leave the
   flags on the objects, but I do not think this one, which happens
   before the main traversal even starts, should pass 0 here.
