Improvements to the "echo"

[prescod]

Can we try (or did we try?) using "#" instead of echo so it's not repeated. Or some other technique to avoid the repetition?

Can we change the prompt?

Provide any options for the task then press <ENTER>

Or change the command to `cci task info <taskname>` to inspect the available options.

Maybe we should add a 'cci task description' command to get a description 1-liner to print in this context.
