   or

       BUFFER defaults to the current buffer. 

   If you think (1) is ok as English, please ignore me; and I'll go back

I believe you are misunderstanding what the function does:

ELISP> (make-variable-buffer-local 'var)
var
ELISP> (local-variable-p 'var)
nil
ELISP> (local-variable-if-set-p 'var)
t

That said, the first line is 70 characters and the maximum allowed is
67.  English is not my native language, but I believe that the "double
if" is not invalid English.  It is probably not great style either.  I
believe that the following new first line fixes both length and style:

   Non-nil if VARIABLE will be local in buffer BUFFER when set there.

That is 66 characters.  I will commit this change if there are no
objections.

Sincerely,

Luc.
