[GRASS-dev] wxGUI command line: white space between - and flag name generates Python error

[Markus Neteler]

Hi,

if one enters (note the white space)

g.proj - w

into the wxGUI cmd line, then Python gets unhappy with:

Traceback (most recent call last):

linux-gnu/gui/wxpython/gui_core/prompt.py", line 399, in

if option[1] == '-':
IndexError

Is there a way to catch that?

thanks
