Subject: wordwrap with negative width
From: smalyshev@gmail.com (Stanislav Malyshev)

Hi!

I've just discovered that wordwrap() (http://php.net/wordwrap) accepts
negative width parameter and treats it as if it was 0. It looks like a
bug, never documented and works in code only by accident as far as I can
see. So, my question is - would it be OK to drop support for negative
width in wordwrap?
