bug#15144: 24.3.50; browse-url silently fails

[Sam Steingold]

browse-url silently fails:

$ emacs -Q
M-x browse-url RET http://gnu.org RET

the *Messages* buffer now has this:

Waiting for process to die...done

The google chrome (the default browser) does not display anyting.

Looks that xdg-open actually returns an error:

xdg-open http://www.google.fr
Error: No running window found

So it is more a bug in xdg-open than a bug in Emacs.
Though the function calling it should use `start-process` instead of
`call-process` IMO.

The other functions calling directly a browser seem to works.
Bypassing xdg-open function work around this bug:

(defvar browse-url-never-use-xdg-open t)
(defadvice browse-url-can-use-xdg-open (around no-xdg-open activate)
  (unless browse-url-never-use-xdg-open
    ad-do-it))

I also have this problem.  And I fixed it by passing NIL instead of 0
as the third parameter (DESTINATION) to CALL-PROCESS in
BROWSE-URL-XDG-OPEN.  T also worked.

Thank you, Paul (and Jānis)!  This was biting me too, and I hadn't had
time to debug it yet.  I was getting ready to, then updated and saw the
fix (which works here).
