sha1_to_hex: properly terminate the SHA1
sha1_to_hex() returns a pointer to a static buffer. Some of its users modify that buffer by appending a newline character. Other users rely on the fact that you can call printf("%s", sha1_to_hex(sha1)); Just to be on the safe side, terminate the SHA1 in sha1_to_hex().
