Rebuilding the search index stops

[Mike Sullivan]

In includes/functions.php, find:

$find[] = '#\[(email|url)=("?)((?(2)[^"]|[^\]\[])+)\\2\]\\3\[/\\1\]#si';

Replace it with:

$find[] = '#\[(email|url)=("??)(.+)\\2\]\\3\[/\\1\]#siU';

Also find:

$find[] = '#\[(email|url)=("?)((?(2)[^"]|[^\]\[])+)\\2\]([^\]^\[]+)\[/\\1\]#si';

And replace it with:

$find[] = '#\[(email|url)=("??)(.+)\\2\](.+)\[/\\1\]#siU';
