This would result in "rgba(255 ,64 ,64 ,128)". I guess the spaces should
be following the comma, so the order of "comma" and "space" should be
reversed each of the three times it is mentioned.

I already sent this to the list on March 20th, and Olli Pettay sent a 
mail a few hours earlier, but both went unnoticed.

2) While we are at it: do we really want a returned value of
    "rgba(064, 007, 00000000009, 128)"
to be legal? I suppose a CSS parser would allow it, but as we're
specifying the exact format here, the spec should probably
explicitly disallow (or even allow?) zero-padded integers.

3) Storage (chapter
http://example.com/:18080 should be http://example.com:18080/
