w3m-view-url-with-external-browser should allow us to edit the URL

[jidanni@xxxxxxxxxxx]

M runs the command w3m-view-url-with-external-browser, which is...

which is great, except that it doesn't give up a chance to edit the URL.
We are just asked y or n.

How about instead just allow us to edit the URL, and if we feel the "n"
feeling, we can just hit ^G.

And if on top of a URL, well, should it maybe still ask us to edit the
URL?...

Or maybe with a C-u argument...
