  New Revision: 66116

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=66116

  Log:
    remove unnecessary code removing CR/LF from range
    
    Remove code that tries to remove CR and LF from Grapheme_Cluster_Break=Control.
    This code is unnecessary because Grapheme_Cluster_Break=Control already excludes
    CR and LF.
