Somehow :setl syn=ON (or even :setl syn=on) seems to set the syntax
highlighting according to the value of 'filetype', but :setl syn?
answers " syntax=ON" or " syntax=on" respectively. From what I see
above it sems to be the intended behaviour. Didn't know that.

As long as there is _no_ off.vim syntax script (and who would install a
syntax script of that name?), the behaviour for an "unknown" syntax is
to highlight everything like the Normal group anyway.


Best regards,
Tony.
