When I do a cross-buffer cut-and-paste from a buffer with syntax
highlighting to one that doesn't have any highlighting I find that
the highlighting from the source buffer is preserved, which I don't
want.
I have not been able to find a way to get rid of this "imported"
highlighting, other than killing the buffer and revisiting the
file, which is pretty annoying. E.g. "M-x fundamental-mode" won't
do it.
Is there a simpler way of getting rid of this unwanted highlighting
(or of avoiding it in the first place)?
