Okay, that works now.

True.  But if they are not distributed (like in git), I would like the
install rules to be just skipped /if/ makeinfo is not available.  So,
if nano.info and nano.html are already there, install them, but if
they are not and 'makeinfo' is absent, don't even /try/ to build them.
I don't see how I can achieve that.

Thanks for the hint.  :)  The specific rule was not needed, as
automake provides it by default.
