bin/dochazka-cli: reinstate --debug parameter

In dochazka-cli, the --debug parameter causes the parser to display,
after each command, the exact tokens/command it recognized, the name
of the implementation function to which the command was dispatched,
etc.

The parameter had been removed by mistake.
