[CM] vertical tab in scheme (make that "bar" not "tab")

[Bill Schottstaedt]

This change is in snd-6.tar.gz at ccrma-ftp and in the sourceforge
CVS repository; there's a script "fix-bar" (I should have called it
"foo-bar") that can change the names from the old to the new forms,
(i.e. fix-bar *.scm or whatever).  I also took the liberty of changing
Dave Phillips' files in the contrib/dlp directory -- hopefully they
survived intact.
