Great, it works!

I just want to mention that it took me some time to spot the TWO changes
in that suggestion. One was easily visible:

--8<---------start----------x--------->8--
("-F", (concat (getenv "XDG_CONFIG_HOME") "/ssh/config"))
     ^^^
--8<---------end------------x--------->8--

The other one not so much: the single apostrophe was replaced by a
backtick:

--8<---------start----------x--------->8--
`("ssh-j"
^
--8<---------end------------x--------->8--

Again, it's my fault that I am not very conversant with Lisp but small
traps like these can be ... frustrating :)
