That's good.  I also vaguely thought it might be possible.

Too bad.  Maybe the administrator is taking a winter vacation?
Anyway, thank you for the new patch.  I wish we could merge it
by the time Gnus v5.10.7 is released.

Currently the default value for `mm-coding-systems-priorities'
is non-nil only in the Japanese language environments, which is
done by examining the value for `current-language-environment'.
Is it able to set `(iso-8859-1 iso-8859-15 ...)' by the same
way?  If so, do you know those language names?
