[PATCH 1/3] Correct test-parse-options to handle negative ints

[Charles Bailey <charles@hashpling.org>]

From: Charles Bailey <cbailey32@bloomberg.net>

Fix the printf specification to treat 'integer' as the signed type that
it is and add a test that checks that we parse negative option
arguments.
