Upon closing a tabbed browsing window, being warned when more than one tab is not blank or has history is useful.  Being warned when fewer than two tabs are not blank or have history is not useful, yet happens frequently.  Blank tabs with no history should not be counted when determining whether or not to warn.

Reproducible: Always

Confirmed on Windows XP; don't know if there are thoughts behind this.

The tricky part is that pages can open a new window with about:blank and then inject content, so we need some sort of indicator that about:blank is unmodified.  Otherwise, this makes sense, but I don't know how often people open a new blank tab and then close a window...
