Fixed codecoverage to not ignore executable lines

Hi @sebastianbergmann,

Finally managed to get a branch and pull request working. Can you please check and merge this?

It fixed issue for code of below type
<?php
$x = 3;
if ($x == 2) {
    echo "test";
    ?> This is for x = 2 <?php } else {
    echo "x!=2" ?> This for x!=2 <?php
}
?>

Earlier like echo "x!=2" will not get covered because of filtering. Now that is taken care of

Regards,
Tarun
