  New Revision: 61064

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=61064

  Log:
    parse.y: Fix locations of regexp
    
    * parse.y (new_regexp_gen): Always set locations
      to include locations of tREGEXP_BEG and tREGEXP_END.
    
      e.g. The locations of the NODE_LIT is fixed:
    
      ```
      /a/
      ```
    
      * Before
    
      ```
      NODE_LIT (line: 1, code_range: (1,1)-(1,2))
      ```
    
      * After
    
      ```
      NODE_LIT (line: 1, code_range: (1,0)-(1,3))
      ```
