Re: Latin-1 non breaking space not highlighted

[Richard Stallman]

    Currently, the definition of ``trailing whitespace'' includes only ASCII 
    whitespace characters.  If we are to broaden this definition to non-ASCII 
    characters, I think we need a more general definition; just adding a 
    Latin-1 NBSP is not enough, IMHO.

What is the syntax code of Latin-1 NBSP?  Is it "whitespace"?
If not, why not?

If it is, then why not make "trailing whitespace" include everything
with whitespace syntax?
