Subject: Re: [PHP-DEV] wordwrap with negative width

I think I answered this question several times, including in the email
you are quoting! If you disagree, please state the matter of your
disagreement, repeating the same question over and over does not help.

If it was expected to be wrapped but is not, then it would be shown on
top of other elements, or break the design layout. Not exactly the best
idea. Since calling it with negative argument makes no sense, there's no
behavior that makes sense. Producing an error means this nonsense
situation is discovered.
