https://dvcs.w3.org/hg/csswg/rev/9fdb78b42060 looks wrong:

whitespace

Consume as much whitespace as possible. If the next input code point
is U+0029 RIGHT PARENTHESIS ()) or EOF, consume it and return the
<url-token>; otherwise, consume the remnants of a bad url, create a
<bad-url-token>, and return it.

So url( a) is a <bad-url-token> ?

Ah, that's why I had the "redundant" early steps - to allow
whitespace only at the beginning or end. I'll revert.
