Re: face for non-ASCII characters

[Ted Zlatanov]

Sorry if I confused you guys.  I set it up to do

(require 'idn nil t)

and later test (fboundp 'idn-is-recommended) which I believe is the
right thing.  autoloading is not required and was confusing me.  If the
user overrides the default and adds 'markchars-nonidn-fun to
`markchars-what' then they'll get an error.  The change is trivial so I
won't repost the whole file.
