"bundle" command disappears if only 0.9.0.pre2 is installed

[topfunky]

Steps:

• Install 0.9.0.pre2
• Uninstall all other versions of the bundler gem
• Run "gem bundle"
• "Unknown command bundle"

Apparently it was renamed to just "bundle" and is no longer a gem plugin.

Is there any chance that you could leave in the previous "gem bundle" command with a deprecation notice?
