695 d96da29b 2005-03-14 devnull  * This is here as a first stab at something. 
696 d96da29b 2005-03-14 devnull  * Run acme with the -'$' flag to enable it.
697 d96da29b 2005-03-14 devnull  * 
698 d96da29b 2005-03-14 devnull  * This code isn't quite right, in that it doesn't play well with 
699 d96da29b 2005-03-14 devnull  * the plumber and with other applications.  For example:
700 d96da29b 2005-03-14 devnull  *
701 d96da29b 2005-03-14 devnull  * If the window tag is $home/bin and you execute script, then acme runs
702 d96da29b 2005-03-14 devnull  * script in $home/bin, via the shell, so everything is fine.  If you do
703 d96da29b 2005-03-14 devnull  * execute "echo $home", it too goes to the shell so you see the value
704 d96da29b 2005-03-14 devnull  * of $home.  And if you right-click on script, then acme plumbs "script"
705 d96da29b 2005-03-14 devnull  * in the directory "/home/you/bin", so that works, but if you right-click
706 d96da29b 2005-03-14 devnull  * on "$home/bin/script", then what?  It's not correct to expand in acme
707 d96da29b 2005-03-14 devnull  * since what you're plumbing might be a price tag for all we know.  So the
708 d96da29b 2005-03-14 devnull  * plumber has to expand it, but in order to do that the plumber should
709 d96da29b 2005-03-14 devnull  * probably publish (and allow users to change) the set of variables it is
710 d96da29b 2005-03-14 devnull  * using in expansions.
711 d96da29b 2005-03-14 devnull  * 
712 d96da29b 2005-03-14 devnull  * Rob has suggested that a better solution is to make tag lines expand
713 d96da29b 2005-03-14 devnull  * automatically to fit the necessary number of lines.
714 d96da29b 2005-03-14 devnull  * 
715 d96da29b 2005-03-14 devnull  * The best solution, of course, is to use nice short path names, but this
716 d96da29b 2005-03-14 devnull  * is not always possible.
