In io.erl the types specified for get_line/1 is
-type prompt() :: atom() | string().
-spec get_line(prompt()) -> iodata() | 'eof' | {'error', term()}.
get_line(Prompt) ->
get_line(default_input(), Prompt).
And that is also what the documentation states.
But in ssh/examples/ssh_sample_cli.erl there is
Line = io:get_line({format, "CLI> ", []}),
Is this a secret unsupported invocation or is it an error in the
io documentation?
If it is unsupported it should not be used in examples.

Hello!
I cannot tell why the io:get_line call didn't follow the documented API,
but ssh_sample_cli.erl has now been corrected.
Best regards,
