Testsuite: Allow input lines starting with ":<cmd>:", like ":sleep:".

This somehow mimics the behaviour of the client tool, but works for
*any* input line that is sent to the application. This reverts the
unfortunate take abusing the client's special notation '>>> '.

Currently implemented:

        - :eval:
        - :neol:
        - :sleep:
