 Improve the parser. Now we understand negative exponents; fixes PR 50768.
 Also handle negative numbers better in general (don't randomly drop
 the sign in a number of cases) and don't choke on exponents > 9.
 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
