Subject: [PATCH] os_posix: Print complete, attempted command line when
 execute() fails
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Previously, only argv[0] was printed which did not provide much
information to the user about why the command might have
failed. Printing the entire command line allows the user to more
easily investigate the problem.
