Subject: [PATCH 1/2] cli: fix top level --help combined with other options
Date: Sun,  8 Mar 2015 18:18:54 +0200
Message-Id: <1425831535-15920-1-git-send-email-jani@nikula.org>
Precedence: list

If the top level --help is combined with other options, help
fails. For example:

    $ notmuch --version --help

    Sorry, --help is not a known command. There's not much I can do to help.

Fix this by adjusting argc and argv appropriately. The help command
ignores argv[0] anyway, so we don't have to set it to "help".
