A mapcalc expression, involving somewhat long(er) temporary map

Any smart ideas on how to post-process this to get rid of all
'tmp.32493.16.tmp.32493.11.tmp.32493.6.' parts?
Standard string manipulation utilities?
I would guess so.
Or, rather, build an "fake" expression with the original map names just
for the sake of having a cleaner history?
Using r.support ?
Looking at your expression, I'm mostly wondering why you don't just use
r.cross to get the same result ... ;-)
