Paul Eggert 5ab29400a4 Don’t signal overflow for (expt 1 bignum) 
Similarly for (expt 0 bignum) and (expt -1 bignum).
The result is always a -1, 0 or 1, so do not signal overflow.
* src/data.c (expt_integer): Do not signal an overflow if
-1 <= X <= 1.  Be clearer about when overflow is signaled.
* test/src/floatfns-tests.el (bignum-expt): Test this.
