This commit alters the meaning of a few previously valid but marginal
inputs (e.g. "3 foot-5 pound" is now treated as "3*-5 foot-pound"
rather than "3*5 foot-pound"; if you want the latter insert another
space) but corrects obviously wrong handling of many more.
Improve previous slightly; while we accept e.g. "meter2" to mean "meter^2",
don't allow "meter-2" to be interpreted as "meter^-2" as that's very
