bash bug? test -r works

["Steve M. Robbins" <steven.robbins@videotron.ca>]

In debugging a shell script, I discovered that bash (and ash)
treat

	test -x 

as true.  Normally, one would use "test -x SOMEFILE", and
I would have expected a bare "test -x" to be a syntax error.
However, both bash and ash return status 0 (true) with no
diagnostics.

In contrast, /bin/sh on SGI's IRIX 6.5 returns a diagnostic

    $ test -x
    /bin/sh: test: argument expected
    $ echo $?
    1

It looks like a bug in bash & ash to me.  Is it?
