I could handle that.  However, I really start to doubt that enabling
xterm-mouse-mode by default in all terminals for which we believe it
makes sense is a good idea.  As we have seen, Xterm Mouse mode has a
very imperfect and unpredictable implementation.  It is basically
impossible to know whether a given type of mouse click is going to be
handled by Emacs or by the terminal without trying it out first (or
very carefully studying the code first).  That is why the Emacs manual
would have to tell people who get frustrated by all of this
unpredictability how to disable the mode.  Also the heuristic we use
to decide when to enable xterm-mouse-mode might miss some terminal
types for which it works.  People using these terminals would still
have to know which function or variable to use to enable it themselves.

I would say, let us keep the mode disabled by default.  If we want to
go through with enabling it by default, I will take care of the Custom
problems.

Sincerely,

Luc.
