process substitution can't be redirected

[Dennis Williamson]

Binary package hint: ksh

This produces a syntax error:

$ grep -H a < <(echo a)
ksh: syntax error: `<(' unexpected

This works:

$ grep -H a <(echo a)
/dev/fd/4:a

Contrast this with Bash and zsh in which both forms work:

$ bash -c 'grep -H a < <(echo a)'
(standard input):a
$ bash -c 'grep -H a <(echo a)'
/dev/fd/63:a
$ zsh -c 'grep -H a <(echo a)'
/proc/self/fd/12:a
$ zsh -c 'grep -H a < <(echo a)'
(standard input):a

ksh version:

$ echo ${.sh.version}
