   * main.c: Add TeX Live version.
   * {main,convert,fread,fwrite,styfile}.c, kana.h,
     mendex.doc, mendex.1: Add a new option -I to switch
     internal buffers for key words to EUC-JP or UTF-8.
   * mendex.1: Fix usage.
   * convert.c: Allow longer words in dictionary.
   * fwrite.c:  Make a buffer size larger.
