haiku/headers/os/support/List.h
Stephan Aßmus b0850e9ba1 * Code and header indentation cleanup
* Added operator== and !=
 * Added check for list != this in operator=
 * Added HasItem() and IndexOf() versions that take const void*, duplicating
   the code, since I didn't want to introduce another function call in these
   potentially time critical methods.
