NSMutableArray removeObjectsInArray

[sakrist]

Wrong implementation of removeObjectsInArray.

If we pass self object to removeObjectsInArray it will remove half of itself objects.

Received array must be copied or converted to set. if it's the same object to receiver, then removeAllObjects.

- (void)removeObjectsInArray:(NSArray *)other
{
    if (self == other) {
        [self removeAllObjects];
        return;
    }

    NSSet *set = [[NSSet alloc] initWithArray:other];
    for (id obj in set)
    {
        [self removeObject:obj];
    }
    [set release];
}
