Electric Shift Lock Mode in Lisp Mode

[Daniel Brotsky <dcb at MIT-AI>]

In ZWEI in System 78.51, ZMail 38.5, microcode 848, 60Hz, on Lisp Machine Four:
In the editor in Lisp Electric Shift Lock Mode: in the middle of a string which
extends over several lines (it documents a function), if the current line
starts with an open paren `(' then Zwei inverts the sense of the shift lock;
that is, things typed inside the string are capitalized and outside they are
lower case.  This is "fixed" by moving the open paren off the beginning of the
line.
