[PATCH] gitweb: make HTML links out of http/https URLs in changelogs

[Kir Kolyshkin <kir@openvz.org>]

It is a common practice to put links to bugzillas, mailing lists, etc. 
in git log entries. The fact that gitweb doesn't make HTML links out of 
that URLs makes following those URLs inconvenient. This patch fixes that 
problem, trying to address cases when URL is enclosed in round or square 
brackets.

Slightly tested on http://git.openvz.org/. Applicable to git-1.4.4.
