textview / test storage string copy problem

[Riccardo Mottola]

Hi,

while debugging SWK on gnustep, Fred found out that we have a problem 
that the string returned by the textview is not a copy.

On cocoa it works, it would be nice if somebody can confirm that Cocoa 
returns a copy.

In NSTextView:
 - (NSString *) string
 {
  return [_textStorage string];
 }

If a copy is needed, should it be tone at the textview or at the 
textstorage level? Matching Cocoa behaviour is of course the goal.
