hack-local-variables

[Luc Teirlinck]

The behavior of `hack-local-variables' has recently been changed.
(hack-local-variables t) used to check, until recently, whether a mode
was specified in the -*- line.  In current CVS, it checks whether a
mode is specified in the -*- line _or_ in the local variables list.
This incompatible change was made without updating the Elisp manual or
mention in the NEWS.  The patch below updates the Elisp manual.  I can
install if desired.

Since this is an incompatible change, should it also be mentioned in
the NEWS?
