[PATCH v2 0/4] add [ as alias for test, fix 0/1 argument handling

[Rasmus Villemoes]

Make 'test' behave a little more like its cousins in other shells, by
allowing the [ ... ] spelling, and while here, fix up the handling of
a single, non-empty argument to comply with POSIX.

v2: update documentation, add a few more test cases.
