note 84794 added to function.preg-replace

I just was trying to make a negated replace with a string NOT being in another string. The code that is actually working: <?php $result = preg_replace('#{(?!disable1|disable2)[a-z0-9]+}#is', '$1', $foo); ?> This code matches on all strings that do NOT start with "disable1" or "disable2" and contain of a-z0-9. It took me several hours to figuere out this very easy example!
