The fact that dl->bufpos can be either a buffer + position or a char count highlights this.

Either we should treat the modeline *entirely* separately, + or we should abstract to something that applies equally well to the + modeline and to buffer text, the things are not enormously different + after all and handling them identically at some level would + eliminate some bugs that still exist (mainly to do with modeline + handling). This problem doesn't help trying to implement gutters + which are somewhere in between buffer text and modeline text. + + Redisplay commentary: Everything in redisplay is tied very tightly + to the things that are being displayed, and the context, + e.g. buffers and windows.
