Problems with longline-mode

[Lennart Borgman (gmail)]

I have seen some problems with longlines-mode (used together with 
nxml-mode). Sometimes the visible marking of new line characters 
disappear, sometimes the wrapping that should be done by longlines-mode 
does not happen.

Have anyone else seen problems of this kind?

(I am still using a CVS version of Emacs, checked out just before the 
release.)
