Test case showing that comma/whitespace is optional between and after arc flags

As per recent W3C SVG WG discussion:

All other browsers (Firefox, Opera, Batik, IE9) treat the whitespace/comma
between largeArcFlag and sweepFlag in the SVG arc path command syntax as
optional.  They also treat the whitespace/comma between sweepFlag and the
coordinate pair as optional.  

Finally only values of "0" and "1" are allowed for the largeArcFlag and
sweepFlag as per the path grammar:

I am attaching a test case.  This test case renders all paths as green in
Firefox, Opera and IE9.  This test case renders all paths as red in
WebKit-based browsers. 

I would like to suggest that WebKit align with what other browsers are doing,
especially considering that the WG considers this as 'proper' behavior.
