my motivation in this case is not driven by the GUI. I would like to
improve CLI logic first, the GUI dialogs are just influenced by that.

General idea for modules which print something to the output.

Two flags:

-p Print in human readable format (can be omitted by default behaviour
of the module)
-g Print in shell script style

If module can print different information (range, title, topo, etc.)
then add parameter `print` or something similar to control the
content. In the case of v.info `print=basic,extent,topo`, for r.info
`print=range,resolution,type,region,units,datum,title`. I think it
would make CLI a little bit clearer. Not speaking about GUI.
