@jam - in line with your recent CL https://codereview.chromium.org/13409003/ ---
note how the CanDownload() WCD method is not actually called from within the
content module at all! It's only purpose is to let chrome/ code talk to other
chrome & extension and CF code.

oh, in that case that's a bug. i had gone through before and removed all such
WCD methods. i may have missed this one, or it may have gotten added after.
either way we should remove this and do it another way.
