From 2d2ad6d0902bb6338f7fc64e52c202439b90f7ce Mon Sep 17 00:00:00 2001 From: Fam Zheng Date: Fri, 18 Apr 2014 14:55:36 +0800 Subject: configure: Improve help behavior Old: There are two paths to show help and exit 1, one is with "-h" or "--help", one is with invalid options. New: Show help and exit 0 for --help. On invalid option, don't show the long help and bury the early "ERROR:" line, just give a message pointing to --help.
