 As for testing -  it's not needed since just looking at the source proves
that everything will work as expected. So don't consider it that unstable.
Also, buggy behaviour will be encountered only by those who use extension to
EXTERNAL command, not by all lynx users.

  What patch you are talking about? Seems there was no such situation (at
least there wasn't much discussion except success story from Eduardo and
command from mattack who told that it would be better to use CERN rules).

  Nobody is going to remove internal mailto: handler - there would be just a
lynx.cfg setting something like EXTERNAL_MAIL:TRUE/FALSE, if TRUE it will call
external wrapper that will be supplied with a lot of mailto: -specific things
like subject, cc:, To:, and filename of the file with body quoted, if any.
  So, security won't suffer.

  It's already stated in my previous mail that lynxcgi/pseudo-proxy won't work
on some environments like DOS/Win (well proxy will work under Win, but it
won't be supplied with all info internal mailto: handler has), and EXTERNAL
handler won't have all info necessary too (subject+cc+To:+body) - so some sort
of support for external handlers of mailto: should be implemented.

 As for original patch that extened EXTERNAL - I don't like it too now, but I
don't insist on removing it from source tree (is it development version or
