It would be better to just use

        my $str = shift;
        return '' unless defined $str;

and neither your change in esc_html, nor the change below should be needed. 
By the way, commit without title? But it would be better if correct it, to
set $co{'title'} to an empty string, either in git_log or in parse_commit.
