RE: [CSS21] Spaces, non-breaking spaces, ideographic spaces and the word-spacing property

Then I propose to update the relevant word-spacing [1] prose from :

        #  Word spacing affects each space (U+0020), non-breaking space (U+00A0),
        #  and ideographic space (U+3000) left in the text after the white space
        #  processing rules have been applied.

..to :

        #  Word spacing affects each space (U+0020) and non-breaking space (U+00A0),
        #  left in the text after the white space processing rules have been applied.
        #  The ideographic space (U+3000) is not affected by word spacing.

I'm quite certain it should affect NBSP. NBSP should behave
exactly as SP except for its line-breaking effects.

Based on Ambrose's reaction, we may need to re-evaluate whether
it applies to IDEOGRAPHIC SPACE.
