No it won't unless you are talking about the current theoretical browser
that supports window.open (completely non-standard) but not target!
(Incidently this is a Frequently Asked Question of the usenet group
comp.lang.javascript and the solution I gave is the agreed answer and many
of us do consider accessibility), it doesn't have any accessibility
problems, the window.open doesn't give a url to open in the window that is
purely from the A HREF tag, return false/true does (certain browsers
ignore it.)

I entirely agree, although some of us do have machine processing
javascript tools - http://jibbering.com/accessibility/snork.html does some
accessibility testing of scripts for example, and I have robots which are
perfectly capable of understanding javascript.
