[GRASS-dev] module GUI: linking G_OPT_M_LOCATION to G_OPT_M_MAPSET

[Yann]

Hi,

I am trying to set a new location (with G_OPT_M_LOCATION) then to select 
a Mapset in that selected location (with G_OPT_M_MAPSET).

My understanding is that on run-time the G_OPT_M_MAPSET will find from 
the running Location, not the one chosen in G_OPT_M_LOCATION just 
before. I guess we should switch environment after G_OPT_M_LOCATION to 
enable selecting from the chosen Location.

g.gui.gcp does it in a wxPython Wizard, which is not command line 
friendly in the long term (command-line launching is also in the TODO 
list of g.gui.gcp btw), so solving it here will solve the g.gui.gcp 
improvement.

thanks for any hint,
Yann
