it now has `lynx' instead of `links' ;-)

The proposal sounds reasonable; my only objection would be that
it doesn't make a difference between X and terminal applications
(like e.g. the XEDITOR/EDITOR variable); an X application might
want to invoke `xterm -e lynx' instead of just `lynx' since the
IO of the latter will be lost if there's no controlling tty.

I guess so; I've now filed it as a feature request on:

Agreed, the description of that is really lacking. The way it
works is that it just forks the concatenation of $WWWBROWSER and
the URL, so it doens't allow for `%s' (in contrast to the .editor
resource for example).

Yup, that would make sense.
