Interpreting as background-size: X auto does have the useful property that it
produces an undistorted rendering.  There doesn't seem to be a comparably
obvious way to interpret background-repeat or any of the 4-value properties to
produce a "good" rendering every time.  The 4-values have an obvious symmetry
argument for repeating that I think doesn't apply here as a general rule. 
Drawing without distortion seems the best default, to me, when the one
specified value in general only has meaning in the context of all the other
surrounding widths (and the aspect ratio of the image itself).

I wasn't paying attention to www-style when the change was made, tho, so I have
no idea what arguments were or were not presented in favor of this default.
