Yeah, that seems really suboptimal, but I'm not sure what the fix should
be.  Converting everything to hex seems rather odd, since that would
make látin and unicode characters also be hexified, which is weird.

I think the right fix is to remove this question altogether from
emacsbug.el, and inhibit the "remove non-printable characters" query
from message.el.

Any objections?

I think the right fix for control characters below 32 is to convert
them to the ^X ASCII representation.

I'm not sure I'd agree enough to make it a promptless default.

I think it might make sense for the bug reports, but I think that (in
general) there's no point in doing any conversion of anything.  I mean,
the mail will be encoded with a proper transfer encoding when sending,
won't it?

Unless one of the sending methods used by emacsbugs doesn't encode
anything.

Yes.  And if not, then it's a separate problem.

So you're fine with just removing the "encode in hex" question?

Not sure I understand, but I'm fine with sending random bytes, without
removing them first and without asking the user, yes.  We can either
assume they'll get QP or base64 encoded down the line or that it doesn't
matter.

FWIW, for me a bug report encoded in base64 is a non-starter.  Even qp
is a turn-off.  But that's me.
