Okay.  My problem was a corner case, then.  [Though it was star-merge
that did this wrong-order adding.]

For me, revlibs are all about getting pristines out of the source
directories.  Pulling directly from a mirror won't save space, because
it'll dump a pristine in my source tree.

I'm glad that revlibs are more efficient than they first appeared to be,
and I hear you that optomization ideas aren't really welcome, even if
they're 2 orders of magnitude.
