bug#20180: Missing documentation about redisplay.

[Lars Ingebrigtsen]

Reading this thread, I think the conclusion here is that the redisplay
stuff is just too low-level and finicky to be meaningfully documented in
the lispref manual.  You really have to read xdisp.c to start to
understand how that works.

And I think that's fine -- not everything can be put into the lispref
manual.  So I'm closing this bug report.
