@defun local-variable-if-set-p variable &optional buffer
This returns @code{t} if @var{variable} will become buffer-local in
buffer @var{buffer} (which defaults to the current buffer) if it is
set there.
This returns @code{t} if @var{variable} either has a buffer-local
value in buffer @var{buffer}, or is automatically buffer-local.
Otherwise, it returns @code{nil}. If omitted or @code{nil},
@var{buffer} defaults to the current buffer.
