Re: 'mule-fonts' hadling (Re: gtk mule-fonts note)
It is documented: C-h C-w. That's all you can count on in 21.5;
AFAIK
this stuff works as it has for many years in 21.4.
It is largely the same in 21.4. Just as with thousands of `fboundp's,
why not replace all documentation with C-h C-w reference, then?
