Fixed add_to_path() to avoid partial path matching.
The function prunes from the PATH/GWMS_PATH occurrences of the path being added to avoid indefinite growth of paths with multiple occurrences of the same path.
Before the fix the pruning could have been removing a partial matches, e.g. /this/path_long would have been removed when adding /this/path.
Added clarification comments
