Job `on_stdout` always waits for new line

[estacioneto]

Is there a way of not waiting for the new line to have the on_stdout handler called? I couldn't find it and I assume it's related to this repeat statement.

My scenario is that I have a command that waits for the user to press return, but its output asking for it is in the same line. The regular vim.uv.read_start function handles that well, but I couldn't make it work with plenary.job.

Thanks in advance!
