It would be nice if this was fixed. Here's the relevant blurb from the standard: "Zero-length line segments must be pruned before stroking a path. Empty subpaths must be ignored."

And a working example (since the URL above is 404):

Note how a red dot (0 length path) is drawn in FF. This is not the case in other browsers.
