Hm. At the command-line, or, I expect (but haven't checked), in an
autocommand, I get the same result (1 in my case) for both parts of
:echo exists('syntax_on') exists('g:syntax_on')
However, _in a function_ the default namespace is the _local_ space, and
there, exists('syntax_on') would always return zero because, _in that
function_, l:syntax_on has never been defined.
Best regards,
Tony.
