[PATCH 4/3] gitweb: Update README that gitweb works better with PATH_INFO

[Jakub Narebski <jnareb@gmail.com>]

One had to configure gitweb for it to find static files (stylesheets,
images) when using path_info URLs.  Now that it is not necessary
thanks to adding BASE element to HTML head if needed, update README to
reflect this fact.

This is update of gitweb/README to fit state after Giuseppe patches.

There is a little problem either with terminology, or with CGI.pm
module itself. RFC 1808 "Relative Uniform Resource Locators" says
that:
  http://git.example.com/cgi-bin/gitweb.cgi  is absolute URL
  /cgi-bin/gitweb.cgi                        is relative URL
                                            but absolute path
  gitweb.cgi                                 is relative URL
                                            and relative path

while CGI.pm (or, to be more exact, its url() method) says:

  url() or url(-full)  returns http://git.example.com/cgi-bin/gitweb.cgi
  url(-absolute)       returns /cgi-bin/gitweb.cgi
  url(-relative)       returns gitweb.cgi (or /cgi-bin/gitweb.cgi)

That is why I used "Full URL"  for $my_url = $cgi->url();
and "absolute URL" (as before) for $my_uri = $cgi->url(-absolute);
in gitweb/README.
