Here's a patch that gives Emacs mouse functionality on a console on GNU/Linux
It does single, multiple, modified clicks and drags. Of course, t-mouse does
thisalready but with this patch Emacs uses a Unix socket to talk to Gpm, rather
than faking events using the client program mev.

I think it is worth installing for this alone but the icing on the cake would
be to add mouse highlighting and mouse tracking.  Of course, I can't quite get
that to work, and I've spent far too much time on it now, trying to get my head
around frame based glyph matrices.

If there is a display expert who could give me a few hints, or even finish it,
I'd be eternally grateful (well I'd say thank-you anyway!).  I've been abusing
x_y_to_hpos_vpos from xdisp.c for use on a text terminal, so that would be a
good place to look.
