Now I have gotten the basic catcode 13 approach to work. Included is a
patch to texinfo.tex, and an ISO-8859-1.def file. I use the same
definitions as latex/misc/isolatin1.sty, except that I stripped some extra
trickery with symbols like @acute@A@acute@ which I didn't understand.
Regards,
/Niels

+% It would also be preferable to have the .def files use some special

+% way, the mechanism could be changed by editing a single macro
+% definition here, without touching the .def files.
