Yes, '+' doesn't have a reserved purpose in the path component, but
does encode a space in the query string. So it doesn't have to be
escaped in the path component and can be used as is (although
percentage encoding is recommended nobody seems to do it).

I don't know. I just observed that I can see the group name
inbox.gcc.libstdc++ in my nttp and imap readers when pointing at
inbox.sourceware.org.

That works! https://inbox.sourceware.org/libstdc++ looks fully
functional now.

Now to figure out how to properly include that patch before the other
sourceware overseers figure out I patched the packaged code in place.

Thanks,
