* 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 "")
Should be easier to update and extend. Not clear that the code for making a string piece is still needed here, since we interpret strings as file names. So this may be further simplified. I hope this also will give us a better handle on some of the file inconsistencies, by isolating the readers for formatted and unformatted files.
