Comment 3 for bug 698535

I want to re-open this, it has broken new-page functionality in xgsch2pcb.

As stated in the original report, we should probably run the new-page hook when a page _cannot_ be loaded from disk, e.g. because the a file specified to open doesn't exist.

Alternative - add some means to invoke gschem to create a new page, and pre-specify the filename to save into.
