DiffItem does nothing

[GoogleCodeExporter]

I have installed NiftyPerforce on Visual Studio 2008 and when I choose DiffItem 
on a file, nothing happens. What do I need to do for this to work? Is this a 
bug?

First, does the file have a diff? If it doesn't, then nothing will happen.
Second, do you have any custom diff options? If so, there is some logic in 
there to make that work, but it will go to the console pane instead.

In my case I figured out I needed to use "p4 save -s P4DIFF" and make it point 
to a batch file, which runs my custom diff utility (beyond compare 3). However, 
is any special configuration required for just the default p4diff.exe utility 
to be used? Before I did any setup work, a unified diff was printed to the 
output pane in Visual Studio instead of opening up P4DIFF.EXE like I expected.

I meant "p4 set -s"
