What bug did that cause in recent versions of makeinfo?

What's to warn about?

This trick is for versions of makeinfo which leave newlines in macro
expansions, since otherwise you will have trouble coming up with
macros that expand into Texinfo directives which need to be alone on
their lines, like "@item" or "@end SOMETHING".
