note 53749 added to function.preg-replace

I've just discovered something very annoying the hard way: (an hour of insanity-checking my code) When using preg_replace (or anyother preg_...function I assume), with numerical quantifiers such as {n,m}, it is imperative not(!) to have whitespace following the comma. Thus: NOT working example: $string = preg_replace('#([search parameters]{2, 2})#', 'replacement', $string); Working example: $string = preg_replace('#([search parameters]{2,2})#', 'replacement', $string); This may be common knowledge for some, but it illuded me - especially as I find it good readabillity practice, always to add a whitespace after a comma.
