All other glob options do show_reference with for_each_ref_in() and
then calls clear_ref_exclusion(), and logically the patch makes
sense.  

What is the "problem" this patch fixes, though?  Is it easy to add a
new test to t/6018-rev-list-glob.sh to demonstrate that "--glob" (or
whatever that clears exclusion list without this patch) works
correctly but "--all" misbehaves without this change?

Thanks.
