[issue:446] Re: *ptex --version should not require texmf.cnf

Hello Karl and all,

The place where texmfcnf.cnf is looked for is

void init_default_kanji (const_string file_str, const_string internal_str)
{
    ...
    p = kpse_var_value ("guess_input_kanji_encoding");
    ...
}

in kanji.c. It is executed (as initkanji()) from maininit().

It looks like "guess_input_kanji_encoding" information is not needed
before parse_options(). So one approach is:

maininit(){
  char *p;
  ...
  initkanji(); // move "guess_input_kanji_encoding" stuff from kanji.c ...
  infile_enc_auto = 2; // "not set"
  ...
  parse_options(...);
  if (infile_enc_auto == 2) {
    // ... to here.
    p = kpse_var_value ("guess_input_kanji_encoding");
    if (p) {
        if (*p == '1' || *p == 'y' || *p == 't')
            infile_enc_auto = 1;
        free(p);
    }
  }
  ...
}
