I would like to reproduce the issue with openssl s_client and just forward this
whole issue to the openssl group.

Yes, or just allow multiple --cert, which doesn't currently work.

I can't suggest a working for --cacert as I don't actually now what it does,
regarding that even the openssl documentation is weak about it as you say.
I just know...

...that --cacert should not change the list of client certs but only the CA db
used for validation.
Having multiple --cert or a merged cert file is also not that correct, as there
is always only one client cert, or maybe multiple client certs if available. The
rest like in my case are CA certs, just used to sign the client cert, required
for validation. Therefore I suggested to add those to something new like
--certchain, similar to the Qt methods. However I'm not completely sure if those
Qt methods do what I expect them to do..
