Re: no empty @xref arg 1?

[Karl Berry]

    When specifying arguments to `Info-goto-node', just
    `(INFO-FILE-NAME)' with NODE-NAME empty is perfectly correct.  Why the
    same should not be allowed in a cross-reference?

Just (INFO-FILE-NAME) for Info-goto-node is essentially a shorthand for
Top(INFO-FILE-NAME).  Interactively, it makes sense to allow shorthands
like this.

However, when writing cross-references in a document, I don't see the
need; typing the three extra characters does not seem at all
problematic.  And that way the not-impossible error of unintentionally
leaving the first arg blank can be diagnosed.

Do you have a practical document where you needed the first arg blank?
It's been five years since the change was made, and you are the first
person to even mention it.

Happy holiday cross-referencing,
