[GRASS-dev] [bug #2969] can wxPython GUI handle order of options for v.type and alike?

I have added conditionalized GRASS 7 code to v.type in CVS to make it
use to= and from= lists instead of type=,,,. It seems to work ok, but
deactivated to avoid breaking the GRASS 6 module interface. In the mean
time we have v.type.sh from the GUI now. Functionality would be lost in
that you could only convert one feature pair at a time.

v.clean tool-order from the GUI is still an issue. Only GUI solution I
can think of is to suggest typing in the command at the gronsole prompt,
as the order can be arbitrary.
