But other "imaginary" example definitions in intro.texi don't use @var.
Nor does any "real" @defspec in doc/lispref use that.

Also, in contrast to the makeinfo program, texinfo-format-region would
produce

 -- Special form: count-loop (VAR [FROM TO [INC]]) BODY...

in both cases, with or without @var.  Perhaps, that's the reason that
nobody noticed at the time?

So is there anything wrong with Drew's revised suggestion (as
I understand it)?
