That does not restrict the amount of users, yes. However,
if I choose GNU GPL, then it might decrease the number of

The web page doesn't explicitly say so but I think so.

Yeah, but I cannot help that. I'm not the only copyright
holder of XEmacs and I cannot change the contents of GNU GPL
or Subversion license, either.

Perhaps these URLs?
Unfortunately, XEmacs module interface is not organized at
all, which means it's API is really complex. :-(
I just hope if ltmodem module of Linux kernel is OK, then
distributing Subverion module might be OK.

Yes, it is an option. I'm guessing that if I add it to
XEmacs, some may want it to be licenced under GPL as well.
I need to ask other XEmacs developers for that, though.
It's a shame that licensing issue prevent distribution of
open source software. If lisp binding which parses command
line client comes with XEmacs or Linux distribution and you
have to compile native binding to use it, it's clear which
one users will use. Oh, well.
