Thanks.  As planned these replaced the partial clone with size
filter thing from Jonathan.  The resulting integration passed the
tests locally so I pushed it out.

By the way, the enhancement in this series made to list-objects.c
had a bit of interaction with the last round of Stefan's "describe
blob" topic when both were merged to 'pu'.  I think I resolved it
correctly, but the merge resolution can use extra sets of eyes.
