FWIW, I still prefer making the emulation of a 3rd button selectable via the
FS_WSTAT mechanism, with the server reporting the number of buttons via
FS_STAT. I've come across quite a few programs that assume that either the
left or the right button can be pressed at the same time as a middle button
(if it's present) - forcing the emulation can break things under these
circumstances. BTW, I remembered my objection to using multiple names - it
meant adding directory manipulation code to the mouse server where none
previously existed. The fd server already had this code, so the additions
to handle additional "files" was pretty straightforward.
