That allows tests to be completely independent of each other, so tests that
change global state — such as modify environment variables, define functions or
aliases, or hash commands — will not affect other tests, without needing an
explicit cleanup step.
This enables testing path-tilde-home with and without $HOME set, which is part
of issue #216.
While at it, convert the test harness to TAP. This fixes issue #180 by adding
support for "not ok 42 # TODO" output.
This commit assumes that 'grep' supports POSIX-compliant -q and -v flags.

In region_highlight, a spec of the form 'i j foo' with i >= j should have no effect.
Before this commit, however, the {$i..$j} range would happily expand to (5 4 3)
if i > j were the case (e.g., i=5 and j=3).
This breaks vanilla-newline.zsh; the next commit will fix that.
