Yeah, maybe. I seem to recall having looked at that a long time ago
and deciding that it wasn't worth the trouble, but the code involved
has probably been restructured since then, so maybe it'd be easier now.
Of course, that would also create a back-patch breakpoint for every
single regression test expected-file, which is doubling down on the
PITA factor in a rather major way.
