201 should glump things up into sub-blocks, each of which

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