[tex-k] texmfmp.c: calledit and the token list

[Hironori KITAGAWA]

Hello all,

Typesetting the file

  % tex calledit.tex
  \def\B{\begingroup\def\A{\undefined}\A\endgroup}\B

and responding "e" to an error causes
> tex:calledit: unexpected if_ptr=5 not in range 1..1,from input_stack[2].namefield=323

When calledit is called, inputstack[2].statefield is 0 (token_list).
According to [307] of tex.web, "statefield is zero" means "getting input
from a token list".

So I think that the inputstack[n] should be skipped in the first for-loop
when its statefield is zero, as in the attached patch.
