I've started a patch for this (and for PR/168 at the same time).

Besides, checking whether the `.info' extension should be used
is the main reason why Automake needs to scan the Texinfo source
(looking for @setfilename).  This prevents Automake to support
generated Texinfo files (that don't exist with automake is run).
If we deprecate `.info'-less files now, we can stop scanning
Texinfo files in the future.
