Subject: [ruby-changes:3495] naruse - Ruby:r15014 (trunk): * encoding.c (rb_enc_init): revert removing SJIS.

naruse	2008-01-13 10:15:32 +0900 (Sun, 13 Jan 2008)

  New Revision: 15014

  Added files:
    trunk/enc/shift_jis.c
  Removed files:
    trunk/enc/sjis.c
  Modified files:
    trunk/ChangeLog
    trunk/common.mk
    trunk/enc/Makefile.in
    trunk/encoding.c

  Log:
    * encoding.c (rb_enc_init): revert removing SJIS.
    
    * enc/sjis.c: move to enc/shift_jis.c, to make encoding name equal to
      filename for convinience of loading lib.
    
    * enc/shift_jis.c: moved from enc/sjis.c.
    
    * common.mk: follows enc/shift_jis.c.
    
    * enc/Makefile.in: ditto.
