Yes, you can be very sure: it is not going to be considered at all. Seems
very easy to me. The only other solution that is not going to break when
someone sets the wrap value a bit tighter (like the already mentioned
visually impaied who uses a very large font) is to add wrapping info to the
message and take that into account before checking the signature.

Personally I think this is also not GnuPG's task but a protocol that plays
on the lavel of MUA's and plugins.

Maybe by adding this information to the message (could be as simple as
adding a header line like "X-PGP-Wordwrap: 72".

This issue has nothing to do with CUI vs. GUI. Maybe the problem is easier
to bypass when lots of CUI programs are coupled, but I don't see any
fundamantal reason why the UI would matter in this case.

Then a mode decent method than changing message contents has to be found to
make it work.

I agree on this point.
