It's going to, but does not necessarily use `browser'.

If a user doesn't have a browser or a viewer that is suitable to
the content type of given url, it tries to simply download
the contents.  The function decides what to do after downloading
the header and examining the type internally, so it doesn't know
whether it is internal or external when prompting a user for a url.
Downloading may take time, or may finish immediately if a cache
is available; maybe the latter is a rare case though.  On those
assumption, what do you think a better prompt?
