No need for a static_cast here.

[Hongbo Min, 2013/07/01 05:39:33]

Since I don't want to rely on the implicit type conversion between WebURL and
GURL.

[abarth-chromium, 2013/07/01 05:53:34]

Why not?  WebURL is designed to implicitly convert to GURL.  Please remove the
static_cast.

[Hongbo Min, 2013/07/04 08:49:36]

Done.
