As a special case, if the //<default-title>// from above ends in a colon, the name of the currently running program will be appended to the default title instead of replacing it.  In the above example, with ''shelltitle "$ |bash"'', if you run pine, the title will change from "bash" to "pine", and back to "bash" when you exit pine.  If you use ''shelltitle "$ |bash:"'', the title will change from "bash:" to "bash:pine" and then back to "bash:".
