Using gvim as editor on Windows 7

[Daryl Lee]

I just bought the newly announced book "GNU Octave Beginner's Guide" and 
discovered I should be able to redefine the default editor.  My preferred 
editor is gvim, and I'm on Windows 7, Octave 3.2.4.  I have not been able to 
work out the syntax for passing a filename to gvim for editing.  Here's what 
I've done:

edit editor "gvim"
edit .octaverc

With that I get "Create process failed..."

So I spelled out the path:

edit editor "C:\\Program Files (x86)\\Vim\\vim73\\gvim.exe"
edit .octaverc

With that I get a nice gvim editor, but no file opened, and this in the console:

warning: edit: some elements in list of return values are undefined
error: matrix cannot be indexed with .

So I add %s to the command:

edit editor "C:\\Program Files (x86)\\Vim\\vim73\\gvim.exe %s"
edit .octaverc

And that has no effect (gvim launched, no file, and same warnings).

I'm sure I'm missing something.  I know the authors of the book targeted 
Linux, so I'm wondering if someone has suggestions on how to do this with 
Windows?
