  Log:
    ruby.c: remove a magic number
    
    * ruby.c (load_file_internal): remove a magic number, which means
      the length of ruby_engine but the value is unknown in this file
      since the variable is in a different file now.  instead, strstr
      should deal with it well, as far as ruby_engine does not contain
      a space and a hyphen.

  Modified files:
    trunk/ruby.c
