description:
Add a new test case to test <> (open for input & output),
includion a test to make sure that the file doesn't get truncated.

Add new subtests to the "incorrect redirections" test case, to
validate correct behaviour of the shell when redirections fail in
various scenarios, including when the redirect is the whole command.

More along these lines are really needed, but this is better than nothing.

All the added tests pass on the /bin/sh currently in netbsd HEAD.
