        Yes, I've been thinking about that.  It has been giving the
URL of mailed local files since the original Lynx without anyone as
yet having complained about that, and the user can see the URL even
if it weren't included in the mailing.  It's only a potential problem
when you access local files directly, via the command line startfile,
a 'g'oto entry, or the DIRED_SUPPORT.  Otherwise, it was an HREF in
a text/html document, and is not likely be a "secret".

        The X-URL always is what was used to retrieve the document.
The Content-Location will be whatever was received via an http(s)
header, and in theory could be different.  If no Content-Location
header was received by Lynx, then it will be the same as X-URL.
The Content-Base is whatever Lynx used when rendering the document,
which may be one sent by an http(s) server, but that would be replaced
by a BASE element's HREF, if present.  If there was neither a BASE
element nor Content-Base header, but there was a Content-Location
header with and an absolute URL, then that is used as the base and
in turn becomes the Content-Base header Lynx sends.  Otherwise, it
also becomes the same as X-URL.
