        src/usr.bin/units: units.c

Log Message:
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.
