Debian provides scripts such as sensible-browser (attached) which can
find an appropriate program using either a user-set $BROWSER or one of
the applicable symbolic links gnome-www-browser, x-www-browser, or
www-browser, which are maintained by the package manager. In my case,
the latter points to w3m.
If sensible-browser exists, we should use it.
