Fix, NSLayoutManager

[Georg Fleischmann]

Hi,

here is a little patch for the NSLayoutManager fixing a problem with  
layout_char. layout_char is unsigned but may become "negative", thus flipping  
over to huge positive. The huge positive value then is not sattisfying the '<'  
comparison.

        * gui/Source/NSLayoutManager.m [NSLayoutManager textStorage:...]:
          keep (unsigned) layout_char in legal range, in case it becomes < 0
