[GRASS-dev] v.outlier

[Markus Metz]

Please try trunk r39785.

According to the comments in the code, the auxiliary table is used to 
store info about overlapping zones and is dropped at the end. The 
auxiliary table is always created and used, also when no output vector 
for display (QGIS output) is given.
