A question came up. Can you create a standard-url, QI it to a nsIFileURI,
then call SetFile(nsIFile*), like:
nsCOMPtr<nsIFileURL>
fileURL(do_CreateInstance("@mozilla.org/network/standard-url;1"));
NS_ENSURE_TRUE(fileURL, NS_ERROR_FAILURE);
fileURL->SetFile(file);
I am leaning to say yes, but I would like some feedback please.
