[GRASS-dev] r57990 breaks r.colors colour selector

[Maris Nartiss]

Hi Martin,
with r57990 on my system after selecting colour from the list, it
doesn't get appended to executed command and thus it's not possible to
set predefined colour with gui.
Probably changes in some other places are needed too.

Python: 2.7.5
wxPython: 2.9.4.1
Maris.
