Re: Beware of modules.

Even if we do not move some things out into loadable modules, I think it would be nice to restructure a lot of the source code for the next major release (after 21.2, whatever that may be) so that things are a little more isolated. Move stuff into (redisplay|event)/(x11|win32|tty) type of thing. This way, if someone steps up to `take over' officially maintaining a piece of code, it can be clear who owns what, and can make it easier for someone to drop in a complete new code drop into CVS.
