Lower-case parentheses

[Moon at MIT-AI (David A. Moon)]

If you want to experiment with lower-case parentheses, load the file MOON;LCPARN
(lower-case-parentheses t) turns it on, an arg of nil turns it off.  () and []
are interchanged in lower-case parentheses mode.  If there is substantial interest
in this it will probably be installed as a standard option you can turn on.

Note that on the new keyboards to arrive in a month or so the round
parentheses will be both where they are now (upper case) and where
square brackets are now (lower case).
