There is no such option in openssh

 |-o keyhostname=example.com localhost:7766

I do not like the hunk in cli-runopts.c, line 681.  The test is
now useless and depends on the order on the command line.

Regarding yours: isn't that much harder to implement?  The nice
thing about this patch is that it is so small and could be carried
along for over four years without having a look :).  I mean, today
with all those docker images and entire vde2 local networks etc.
the need as such can easily be seen as something ridiculous,
i know...

Ciao!

I want to point out that Konstantin Tokarev was Cc:d in my
message, his name has been stripped by the ML.
