Three-button mouse emulation on OSX (was Re: Enhancement for Emacs on Mac OSX)

[Steven Tamm <steventamm@mac.com>]

So I'm getting around to look at this and I have a couple suggestions:

- I don't like the use of positive and negative numbers to represent 
the variable.  I'd much rather have symbols like nil, t, and "reverse" 
(or something like that).  "t" would correspond to the Apple X11 
implementation where option is the middle button and command is the 
right button (what was positive in your implementation).  "reverse" is 
self-explanatory.

- What should happen if both option and command is clicked?  With X11, 
the mouse-3 wins, that should probably be the behavior (in the patch, 
option wins).

- Right now the patch here would require carbon events (i.e. it 
wouldn't work on OS9).  Is anyone out there using OS9 that would like 
3-button emulation?  Is anyone using emacs with OS9?  The change would 
be fairly trivial, but I'd like some testing since I don't even have 
classic installed.

All opinions welcome,
-Steven
