Subject: [PATCH v2 3/8] ui-repolist: Create context structure for
 cgit_print_repolist()
In-Reply-To: <1457133901-12998-1-git-send-email-tim.nordell@logicpd.com>
References: <1456520339-32708-1-git-send-email-tim.nordell@logicpd.com>
 <1457133901-12998-1-git-send-email-tim.nordell@logicpd.com>
Message-ID: <1457133901-12998-4-git-send-email-tim.nordell@logicpd.com>

This is in preparation of moving the code that iterates over the
repository list into a walk pattern.  This walk pattern will permit
other views on the repository list more easily, such as a section
only list.
