Thanks.  A few minor comments and a question.

> +@cindex definition, showing a macro's

That sounds awkward.  Suggest "@cindex definition of a macro, showing"
instead.

> +@item info macros @var{linespec}
> +Show all macro definitions at the location of @var{linespec}, and describe the

Suggest a slight rewording:

  Show all macro definitions that are in effect at the location
  specified by @var{linespec}, and describe ...

> +@cindex definition, showing a macro's

It's not useful to have identical index entries so close to one
another.  I suggest to remove the second one.

> +Show all definitions of the macro named @var{macro}, in the current scope,

It might be better to say "... definitions of the named @var{macro} ...".

Also, what is the "scope" of a macro?
