Therefore it really needs to be in, as df63fb also by Giuseppe
(gitweb: use href() when generating URLs in OPML) is already in,
and I think gitweb would generate broken OPML and TXT links without
this patch.

I think it is quite robust solution and it makes sense; we use
shortcuts http://git.example.com for projects_list page, and
http://git.example.com/path/to/repo.git for overview 'summary'
action for a project, therefore pathinfo has to look like the
following: http://git.example.com/repo/action/hash with "action"
_after_ "project".  And there is also matter of backward compatibility
of URL (URLs shouldn't break).

Anyway, we have $home_link for default project_list page, which
is path_info without project, and query without query string...
