That certainly sounds like it could use improvement. I think I've  
always "quit the editor and hit control C"

But really, the editor-running bit should be able to sense if you  
haven't changed the file.

I'd love a patch. Possibly something which optionally uses  
Proc::InvokeEditor if it's installed or cargo-cults the logic from lib/ 
SVK/Util.pm (in the svk codebase, which happens to be something I have  
with me on the plane ;)
