Usage text says ObjectSpace is both enabled and disabled by default
-------------------------------------------------------------------
Key: JRUBY-1740
URL: http://jira.codehaus.org/browse/JRUBY-1740
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.1
Reporter: Ryan Fowler
Attachments: objspc_usage_patch.diff
Both "run with ObjectSpace disabled" and "run with ObjectSpace enabled" are
marked as default in the usage. It appears that ObjectSpace is disabled by
default, so the patch just removes the "default; " text from the +O option.
