Subject: [PATCH 04/26] parse_arg(): Really test that argument is properly terminated
Date: Mon, 10 Mar 2014 13:46:21 +0100 [thread overview]
Message-ID: <1394455603-2968-5-git-send-email-mhagger@alum.mit.edu> (raw)
In-Reply-To: <1394455603-2968-1-git-send-email-mhagger@alum.mit.edu>
Add a docstring to the function incorporating the comments that were
formerly within the function plus some added information. Test that
the argument is properly terminated by either whitespace or a NUL
character, even if it is quoted, to be consistent with the non-quoted
case. Adjust the tests to expect the new error message.
Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu>
