Bug-Description:

Process substitution incorrectly inherited a flag that inhibited using the
(local) temporary environment for variable lookups if it was providing
the filename to a redirection.  The intent the flag is to enforce the
Posix command expansion ordering rules.

Patch (apply with `patch -p0'):
