308Proliferation of casemapping is bound to be buggy.

312Possible cleanups:
313more use of lambda/sequence for trivial functions
314rename buf* to wind* to match manual's terminology (nobody but emacs uses "buffer" to mean "window"...)
315move cur_buf global to a buflist attribute
316use the new scheduler for schedule_*; use delayed redraw to perform well under message floods
