If the whole string needs to be prompted, then you just put
```${GUAC_PROMPT}``` in for the whole string. In Guacamole null or empty
values indicate the absence of a parameter and delete that parameter from the
underlying database table (in the JDBC modules, anyway), so prompting for an
empty value would not be practical and would interfere with some of the basic
ways in which parameters are evaluated, aside from which it isn't really
necessary.
