[GRASS-dev] requring explicit input=-

[Hamish]

re. r48434  (and a number of other places)

it's a PITA to have to type input=- all the time from the command
line in places where it can be readily inferred.

if the change is intended to make sure the option turns up on
the required tab(?), please see ticket #886 "improve module wxGUI
tab logic" for discussion on a proposed solution which does not
make the CLI experience more annoying.
