the reason it;s not in sh(1) is that sh(1) attempts, not entirely
successfully, to describe the functionality of a posix sh. other
features are not described.
however sh(1) actually supports the same functionality as ksh(1) (it's
the same binary after all), except for a few differences.
the upshot is /bin/sh can do more than is described in sh(1). and sh(1)
is, by necessity, not one million percent accurate.
