[GRASS-dev] Unix-isms in gis_set.tcl

[Paul Kelly]

gis_set.tcl (the location and mapset browser that appears when GRASS is 
started in GUI mode) contains "exec ls" in a few places that stops it from 
working on native Windows without Msys. Has anybody done any work on it 
and would know how to fix those? I'm sure there must be a Tcl command to 
list a directory but I can't find it by searching on Google.

Also gis_set.tcl seems to return the same exit status if either Enter 
GRASS or Exit is clicked - is this true? I was trying to check the 
%errorlevel% variable in a Windows batch script to avoid starting gis.m if 
enter was clicked, but it always seems to be 0.
