* TEDIT-FIND, TEDIT-OFD: Read old-format TEDIT files
TEDIT-OFD also traps non-stream TEXT arguments that should no longer propagate
* EDITKEYS: Only BKSYSBUF when TEDIT has the TTY
Also, changed the name from Function Keys to Tedit Keys, made the shrunk window open on left-click
* COMPAREDIRECTORIES: better format when one of the columns is empty
* GITFNS: "cob next" asks to confirm the parent branch
* TEDIT-FILE: Pass TEXTSTREAM to TEDIT.GET.OBJECT
* TEDIT-FILE again: same problem in readers for old formats
* Eliminate (OPENTEXTSTREAM "")
* TEDIT files: deleted from library/, renamed to library>tedit.TEDIT-xxx
* PSEUDOHOSTS: Error if file won't open
* LOADUP-*, MEDLEYDIR, UNICODE
Adjustment for TEDIT-xxx, plus moving UNICODE to the beginning of LOADUP-LISP, with UNICODEDIRECTORIES creating in MEDLEYDIR
