gosh, i've always hated csh's ignoreeof so much that it never occured to
me to try to make it work in es.  the problem with the exec/redirection
approach is that the input routines used in %parse explicitly ignore
redirections.  (we had this discussion with Donn Cave as a major participant
back around the time of the 0.74 release.)

try something like

	%interactive-loop < /dev/tty

but i don't make any promises.  i'll look into it.
