[PATCH 4/5] gitweb: Add git_url subroutine, and use it to quote full URLs

From: Jakub Narebski <jnareb@gmail.com>
Date: 2006-09-26 09:58:41
Add git_url subroutine, which does what git_param did before commit
a2f3db2f5de2a3667b0e038aa65e3e097e642e7d, and is used to quote full
URLs, currently only $home_link.

It will also be used in patch inspired by
  "[RFC][PATCH] gitweb: Make the Git logo link target to point to the homepage"
