[PATCH] Remove --no-gui option from difftool usage string

From: Denton Liu <liu.denton@gmail.com>
Date: Feb 4, 2017, 02:56 UTC
Message-ID: <20170204025617.GA9221@arch-attack.localdomain>

The --no-gui option not documented in the manpage, nor is it actually used in the source code. This change removes it from the usage help that's printed.
