Hi Bartosz,

Tramp doesn't handle sshconfig includes. However, you can emulate it
yourself with the following snippet in your .emacs (untested):
Hmm, there was an error in the snipptet. I've reworked it, and added to
the Tramp manual (pushed to master):

4.18.1 Using ssh config include for host name completion
--------------------------------------------------------

OpenSSH configuration files can use an ‘Include’ option for further
configuration files.  Default TRAMP host name completion ignores this
option.  However, you can configure this yourself.

    Given, your ‘~/.ssh/config’ file contains the following option:

      Include ~/.ssh/conf.d/*

    The following code snippet in your ‘.emacs’ uses all files in that
directory for host name completion:

      (tramp-set-completion-function
       "ssh" (append (tramp-get-completion-function "ssh")
                     (mapcar (lambda (file) `(tramp-parse-sconfig ,file))
                             (directory-files
                              "~/.ssh/conf.d/"
                              'full directory-files-no-dot-files-regexp))))

    This code snippet does it for the ‘ssh’ method.  If you replace
"ssh" by "scp", it does it also for that method (or any other method
you like).

Best regards, Michael.
