197 Chuck, I think you should redo this. It should not be the

199 the different faces. The generic stuff in redisplay-output.c
200 should glump things up into sub-blocks, each of which

257 /* Modeline commentary: IMO the modeline is handled very badly, we
258 special case virtually *everything* in the redisplay routines for
259 the modeline. The fact that dl->bufpos can be either a buffer
260 position or a char count highlights this. There is no abstraction at
261 all that I can find and it means that the code is made very ugly as
262 a result. Either we should treat the modeline *entirely* separately,
263 or we should abstract to something that applies equally well to the
264 modeline and to buffer text, the things are not enormously different
265 after all and handling them identically at some level would
266 eliminate some bugs that still exist (mainly to do with modeline
267 handling). This problem doesn't help trying to implement gutters
268 which are somewhere in between buffer text and modeline text.
270 Redisplay commentary: Everything in redisplay is tied very tightly
271 to the things that are being displayed, and the context,
272 e.g. buffers and windows. According to Chuck this is so that we can
273 get speed, which seems fine to me, however this usage is extended
274 too far down the redisplay routines IMO. At some level there should
