* Duplicate POSTSCRIPT files in LispUsers and LispUsers/POSTSCRIPT
* DICOLOR on LispUsers is old version uncompiled 1985; version on internal library is newer
* missed PS-TTY in the postscript files
* Fix .gitignore no longer need diff filter; remove odd extra ~ file
* Verified POSTSCRIPT lispusers subdirectory redundant (not same hash because of EOL. POSTSCRIPT-old apparently was older version, copyright not venue
* Save postscript-old in obsolete
* move internal/library/DICOLOR to obsolete
it took a long time to figure out how to restore old versions, using the './scripts/restore-versions file'. Now that it's there and tested it should be ok to remove them from new 'git clone' of medley
* Not 100% sure about this one, looks like proposed change not sure if it was taken o abandoned; no referenced
* YREM.CM was used with old loadup process; P4A.scn isn't referenced, looks like junk
