ruby--ruby/lib/rubygems/commands/cleanup_command.rb
drbrain 3434676e9e * lib/rubygems: Import RubyGems 1.8.7:
Added missing require for `gem uninstall --format-executable`.

	  The correct name of the executable being uninstalled is now displayed
	  with --format-executable.

	  Fixed `gem unpack uninstalled_gem` default version picker.

	  RubyGems no longer claims a nonexistent gem can be uninstalled.

	  `gem which` no longer claims directories are requirable files.

	  `gem cleanup` continues cleaning up gems if one can't be uninstalled
	  due to permissions.  Issue #82.

	  Gem repository directories are no longer created world-writable.
	  Patch by Sakuro OZAWA.  [Ruby 1.9 - Bug #4930]
