[css-text-3] computed value of word-spacing:normal

[frivoal]

the propdef table of word-spacing says:

Computed value: the keyword normal or an absolute length

The definition of normal says:

Computes to zero.

These are contradictory. I suspect we want to align with letter-spacing. In that case, we should keep the prose, fix the propdef table, and add:

For legacy reasons, a computed word-spacing of zero yields a resolved value (getComputedStyle() return value) of normal.

If not, we should change the prose to "behaves as zero" instead of "computes to zero".

No, this is a case where it really does compute to zero. Fixed the Computed value line. (letter-spacing was different because in CSS2 0 and normal had specified different behaviors, but that's not true for word-spacing.)

(I'm guessing this error was introduced when we revamped the computed value lines in September.)
