  New Revision: 44825

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=44825

  Log:
    * string.c: refactoring, especially about string flags.
    * string.c (STR_UNSET_NOCAPA): removed.
      Use FL_UNSET() with STR_SHARED.
    * string.c (rb_str_capacity): check STR_SHARED directly
      beacuse it is not a embed string.
    * string.c (rb_str_modify_expand): ditto.
    * string.c (rb_str_shared_replace): use STR_SET_SHARED().
    * string.c (str_make_independent_expand): remove STR_UNSET_NOCAPA()
      because `str' is not shared string.
