RFR : 80111342 : hgforest.sh : 'python --version' not supported on older python

[Mike Duigou]

Hello all;

Brad Wetmore noticed that yesterday's fix for 8011178 did not work on older versions of python which lack support for the --version long option. Enclosed is a patch which uses the more widely supported -V option instead.
