$lispdisp and stringdisp



While looking at something else, I noticed there are variables
lispdisp and ?stringdisp, and are actually documented.

Is there a reason that lispdisp is false?  It seems more useful for
lispdisp to be true so that you can distinguish maxima symbols and
Lisp symbols.  If you only use maxima symbols, then you won't notice.

Also, should ?stringdisp really be stringdisp (aka $stringdisp)?  I
also find it annoying that if I enter "a string", maxima display it as
"a string", without the quotes.  

At the various least, I think stringdisp should be a maxima variable
instead of a Lisp variable.  Any objections to renaming this to
$stringdisp?

Of course, I can always change these myself in my startup script, but
I think the defaults should be different from what they are now.
