Subject: [PATCH 1/4] Allow detached form (e.g. "-S foo" instead of "-Sfoo") for diff options
Date: Tue, 27 Jul 2010 23:21:56 +0200	[thread overview]
Message-ID: <1280265719-30968-2-git-send-email-Matthieu.Moy@imag.fr> (raw)
In-Reply-To: <1280265719-30968-1-git-send-email-Matthieu.Moy@imag.fr>

This patch does not handle --stat-name-width and --stat-width, which are
special-cases where IF_LONG_OPT do not apply. They are handled in a
separate patch to ease review.
