* mpz/iset_str.c: Initialize _mp_size to 0, in case no digits in
string; this makes it the same as a separate init and set_str.
This showed up in the INSTALL demo program, where typing garbage
arguments like "./a.out xx yy" to the second version of the program
produced a segv. In any case it seems like a good idea for the
combined init/set functions to be identical to separate calls.
