Well. I don’t think much of the nnmail-pathname-coding-system idea, from my
perspective it in itself is a bug, it should not be overriding
file-name-coding-system. It is not being a very good citizen to use
non-standard encoding for path names in a given directory without very good
reason. It does not look like Yamaoka is going to come around to that
perspective, though.

With the change to the XEmacs 21.5 sources above, the consequences of the
use of nnmail-pathname-coding-system are not as serious as they used to be,
for non-Gnus code; the consequences of the use of
nnmail-pathname-coding-system remain as bad as they used to be for the Gnus
code, because since nnmail-pathname-coding-system is normally nil, the
binary coding system will be used for all file names corresponding to group
names.

With the macro as proposed, Gnus users on beta XEmacs will no longer see the
consequences of the use of nnmail-pathname-coding-system for non-Gnus code.
