You're right. I've made a faux pas, I shouldn't have done that.

Sorry Kris, the change is reverted; in fact, the following documents back
up my original implementation choice:
- http://mathforum.org/library/drmath/view/53194.html
-
http://math.stackexchange.com/questions/491933/exponent-rules-with-negative-numbers
-
http://math.stackexchange.com/questions/68833/what-does-22-evaluate-to/68834#68834

If the conceptual design of php is that unary operators must bind stronger
than any binary operator, we would have to restart the vote but I'm hoping
that won't be necessary.

I shouldn't make decisions before coffee. Apologies for the confusion!
