Fix for wordwrap()

Hello. Maybe this is the intended behavior, but wordwrap()'s behavior is a bit illogical on PHP 4.3.1, as it does only break after a plain whitespace, not after punctuation, \n, etc. Here's a trivial sample : $a = "wwwwwwwwwwwwwwwwww\nphprules\nwwwwwwwwwwwwwwwww"; print wordwrap($a, 10, ' ', 10); Output : wwwwwwwwww wwwwwwww p hprules ww wwwwwwwwww wwwww The following trivial patch makes wordwrap() wrap after any non-alphanumeric charater. Output after application of that patch : wwwwwwwwww wwwwwwww phprules wwwwwwwwww wwwwwww Best regards, -Frank.
