- Match the ordering of the non-tool-specific options in the usage message with the order in the user manual. As a result, we now always print --alignment and --trace-malloc in the core's usage messages, which saves malloc-replacing tools from doing it themselves (and brings it in line with options that only apply to error-collecting tools). - Improved the presentation of the Vex options with --help-debug. - Removed documentation of -d in the manual because it's a debugging-only flag. - Documented --read-var-info in the manual. This fixes bug 201169. - Renamed --auto-run-dsymutil as --dsymutil and documented it in the usage message. - Fixed an XML error in manual-core-adv.xml. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@10703
