- handle signs on integers properly,

- make sure error messages for bad integers are moderately sensible
- handle test ! "abc" -o "abc" (This should evaluate to true)
  (and similar cases) ie:
  and/or operator test added to POSIX special case processing.
- more test cases added.

Based on: Work done on 1.x's test(1) by Andrew Moore and Adam David.
