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

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().
