[CODE] is_number()

  ok, some of you may not wanna use this, but i did.
the idea behind it : I got sick of not being able to test
for Negative values with is_number() although atoi() allowed
them.  so, i "fixed" up is_number() to allow - numbers.

here's the code,
it's a small addition to is_number() in interpreter.c
put this at the beginning of the function (before the while{} statment)
and it should now allow you to send (normal) negative numbers to is_number
ie  -1 is a number, but --1 or ---1 is not (as per atoi() )
hope you enjoy it.

if (*str)
  if(!isdigit(*str) && *(str++) != '-')
    { return 0; }
else return 0;
