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

From: Namhyung Kim <namhyung@kernel.org>
Date: Jul 3, 2012, 06:02 UTC
Message-ID: <1341295377-22083-4-git-send-email-namhyung@kernel.org>
In-Reply-To: <1341295377-22083-1-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: 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 which has more than 8 (hex-)digit characters would set a wrong hyperlink like [1]. Fix it by not using format_log_line_html().
