[PATCH] Fix the --show-commands option.

[Christian Mauderer]

From: Christian Mauderer <Christian.Mauderer at embedded-brains.de>

If the --show-commands is set, the cmd-string is joined for printing.
This breaks a later Popen call that expects an array instead of an fully
assembled string. This patch fixes the problem.
