NSProxy forward invocation

[Stefan Urbanek]

The NSProxy forwardInvocation looks like:

- (void) forwardInvocation: (NSInvocation*)anInvocation
{
  [NSException raise: NSInvalidArgumentException
              format: @"NSProxy should not implement '%s'",
                                GSNameFromSelector(_cmd)];
}

I think that the message should be rather something like:
              format: @"NSProxy does not implement '%s'. Subclasses
should implement the method.",

at first look, the original message is a bit confusing, as I first
thought, that I should not implement that method too.

Regards,

Stefan
