minor error in tables.c

[Angelo Borsotti]

Hello,

I think there is  minor error in tables.c, function pack_vector, line 676:

      for (j = lowzero - from[0]; ; j++)

This line should be:

      for (j = lowzero -  state_number_as_int(from[0]); ; j++)

7 lines below it, state_number_as_int (from[k]) is added to j. Thus, either
we
always add the values contained in "from" as converted by
state_number_as_int()
or never do it.
Currently, the function  state_number_as_int() simply returns its argument,
and this means that the error never shows up, but if in the future it will
be changed
the program would behave incorrectly.
