  New Revision: 59926

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=59926

  Log:
    Find.find -> Use Dir.children instead of Dir.entries
    
    Dir.children is available since Feature #11302.
    Find.find can use of the new list (having no '.' neither '..' entries),
    making now superflous an if statement.
    
    This change can improve the performance of Find.find when the path
    has lots of entries (thousands?).
