It's the same thing just a bit more verbose. I like a bit of
redundancy, this "English" protocol thing can be rather ambiguous...

Yes, that's the idea. It's confusing at first, that for a given
destination some elements of the configuration for that session will
come from one Host "statement group" and some will come from others.
It's actually a good design, once you get your head around it.
But difficult to express succinctly, the patch I sent could also
use a tweak to capture this better.

At the risk of sidetracking you... I don't know if this is a lot of
work or exists already, but it might be useful to have an option to
ssh like --config-summary or --show-config that prints the accumulated
configuration from all the inputs (commandline, $HOME/.ssh/config,
/etc/ssh/ssh_config, compilation) and exits. "-O" looks to be free...

ok, thanks.
