Re: [jimb@red-bean.com: Redisplay bug in 21.2.90.1]

[storm@cua.dk (Kim F. Storm)]

I tracked this down to a bug in `insert' which doesn't
adjust END_UNCHANGED in case the insert happens in the
unchanged region.  This happens if require-final-newline
it t (e.g. in c-mode) when doing save-buffer.

I just committed a fix on HEAD.

I guess it isn't serious enough to include on RC branch...?
