[PATCH 2/2] gitweb: make logo optional

[Jonathan Nieder <jrnieder@gmail.com>]

Some sites may not want to have a logo at all.  In particular, git
instaweb can benefit from this.

While at it, use $cgi->img to simplify this code.  (CGI.pm learned
most HTML4 tags by version 2.79, so this should be portable to perl
5.8, though I haven't tested.)

Eric liked an earlier version of this patch that did not use
$cgi->img.
