Indeed, I forgot to add "fido-vertical-mode" to the recipe, sorry about that.

What I type is this:

emacs -Q
fido-mode
C-x C-f
//ssh:hostname:~/
DEL

for me, this then deletes the whole line. 

fido-mode
C-x C-f
//ssh:hostname:/etc/
DEL
DEL

also deletes the whole line, maybe that is what is suppoused to happen?

Thank you!!
