解决方案
Well, it's late, but I'll post my answer in case some other poor soul is struggling with this.

I''ve been struggling with this all day, and finally found the answer at cocoabuilder

In summary, what I did was, in my text view delegate:
- (BOOL)textView:(NSTextView *)aTextView doCommandBySelector:(SEL)commandSelector {
    if (commandSelector == @selector(insertTab:)) {
        [aTextView insertText:@"    "];
        return YES;
    }
    return NO;
}
Seems to work fine.  

Undo works also.
