Darn it, it does work.  Argghh... I already included a here-file patch
with my latest release:
    http://home.eol.ca/~parkw/index.html#herefile
    http://home.eol.ca/~parkw/index.html#here_file

Usage:
    cat <<<< file
    herefile < file
    herefile file


Hi Chet.  Off topic... I'm currently considering adding GTK+ interface
to Bash, so that you can do basic "dialog" stuff in Bash directly.  But,
if it's only dialog stuff, then there isn't much point, because you can
just use real 'dialog' or 'Xdialog'.

Have you come across any project that tries to add GUI features to any
shell?
