Patch

The new option added and moving the always used SSH options into a common
array LGTM, but there is one cleanup I would like to see done as part of
this patch =)

While doing modifications here, could we change this to pass the array of
command+arguments to IO.popen instead of using a command string that will
be passed through the shell? The “ssh” invocation itself does not need to
go through the local shell — the remote command (“cmd” here) will still
run in a shell remotely because that's how SSH behaves.

Sure thing! While here I also changed the next snippet to not open-code a read loop.

Not sure if placebo effect, but this does look more readable to me, as a bonus :-}
