Log Message:
Sorry, barked up the wrong tree.

gtexinfo 6.7 appears to default to utf8, and error out on non-7bit
ascii gremlins. Fixing those lets the texinfo files compile (with
warnings) both with the NetBSD base makeinfo and the v6.7 pkgsrc one.

OTOH, I don't have to remove the patches I forgot to add in the
previous commit...
