Yeah, I considered the first variant. Something like
(exec test -r /dev/fd/3 3</dev/null) would be close to what I want
for the test I was looking at.
It doesn't protect you from pathological strict-Posix systems that
have /bin/test as:
#! /bin/sh
# or /bin/bash
test "$@"
(like, say, Solaris)
but the number of systems with such a test implementation and bash as
/bin/sh and no /dev/stdin is probably small enough to defer the
complication of a C program.
