I can reproduce the behavior for all Emacsen down to Emacs 25 (the
oldest I have a running copy of), so I guess it didn't work ever. The
problem is, that `ffap-guesser' returns "ssh:user <at> server:/home/test",
which looks like a relative file name. Therefore, it is expanded to the
default directory "/tmp/".

I have no idea about ffap.el and thingatpt.el, so I fear I cannot do too
much. Somebody else who knows these libraries might fix it.

Best regards, Michael.
