A library function should not force the application to exit. In the current implementation tep_filter_add_filter_str() calls exit() when a special "test_filters" mode is set, used only for debugging purposes. When this mode is set and a filter is added - its string is printed to the console and exit() is called. This patch changes the logic - when in "test_filters" mode, the filter string is still printed, but the exit() is not called. It is up to the application to track when "test_filters" mode is set and to call exit, if needed.
