[xdebug-general] Weird behaviour with conditionals

Hello,

I'm currently developing a code coverage measurement system using Xdebug,
Phing and PHPUnit2,
and I've stumbled on a few peculiarities regarding Xdebug.

My tool currently measures the amount of methods in a set of classes covered
by testcases, and I
would like to expand this to statements and conditionals covered (similar to
Clover). However,
whenever if/else if blocks are encountered by Xdebug, the code coverage
report seems incorrect.

The following code is an example:

<?php
    function a($b)
    {
        if ($b == 0)
        {
            return true;
        }
        else
        if ($b == 1)
        {
            return false;
        }
    };

    xdebug_start_code_coverage();

    a(1);

    xdebug_stop_code_coverage();
    print_r(xdebug_get_code_coverage());
?>

The output is:

Array
(
    [/var/www/experiment/xdebug.php] => Array
        (
            [4] => 1
            [11] => 1
            [17] => 2
            [19] => 2
        )

)

It could very well be a PHP bytecode thing, but imho lines 8 and 9 (the else
/ if ($b == 1) statements)
should be in the code coverage results as well.
