[PATCH v2 3/3] gitweb: Add support to Link: tag

From: Namhyung Kim <namhyung@kernel.org>
Date: Jul 4, 2012, 02:47 UTC
Message-ID: <1341370046-19913-3-git-send-email-namhyung@kernel.org>
In-Reply-To: <1341370046-19913-1-git-send-email-namhyung@kernel.org>

The tip tree is the one of major subsystem tree in the Linux kernel project. On the tip tree, the Link: (or similar Buglink:) tag is used for tracking the original discussion or context. Since it's ususally in the S-o-b area, it'd be better using same style with others.

Also as it tends to contain a message-id sent from git send-email, a part of the line would set a wrong hyperlink like [1]. Fix it by not using format_log_line_html().
