bug#7510: 23.2; negative "left" parameter of initial-frame-alist interpreted incorrectly

["Jan Djärv" <jan.h.d@swipnet.se>]

It seems the X|YNegative handling code was lost in Emacs 23.
It is easy enough to fix, but shall this be fixed in the emacs-23 branch or 
just the trunk.  It is a regression from Emacs 22, but nobody noticed it in 
Emacs 23.1 AFAIK.
