Hello Ted,

Sorry, I saw the message but didn't get a chance to act on it. Writing a
joking remark on a mobile phone takes much less time and effort...

Anyway,

I toyed with this idea, and even implemented something of the sort, but
from a bit different different direction - I added another replacement
variable - %c - and made the list tls-program now contain pairs with
(string . value-of-c), e.g. ("gnutls-cli %c %T -p %p %h" . "--x509cafile")
have both %c and %T replaced (together) as appropriate.

The problem with this approach is, what about people who customized this
setting? So, I made it backward compatible with the old standard.
Eventually however, it turned into a an ugly big mess due to the backward
compatability and I decided against submitting.

There is a similar problem of backward compatibility in your approach -
what if someone customized it in such a way that wasn't expecting an
argument to be removed, and it would create a vulnerability in their setup?
I also don't see a simple way to do it nicely, but have no objections on
those grounds, of course.

Finally, I would do the patch but am uncertain whether it would be better
to wait for your results from emacs-devel and remove the ssl3 bit as well
(or just go ahead and do it). Let me know and I'll send the appropriate
patch.

Best,
Kosta
