I prefer Texinfo, since it shows things that are not visible in the
text output (such as indexing and markup that only shows in the
printed version).

The notion of ``empty response'' is not described anywhere in the
manual, AFAICS.  (Yes, this is not directly related to the changes you
are proposing, but I'd like this to be fixed as a side effect.)
