I think the architecture wants you to open the file in the action. Then
feed it to the editor as an IEDitorInput. That way you are not already
opening the editor when you decide you can't open it because the file is
corrupt.
At the same time, IEditorInputs are supposed to be light weight.
IEditorInputs can be held by the architecture to support the recently
opened file menu I think. So I am not sure the preferred or proper way.
I open the file within my editor, and if it fails, I have a background job
that will close my editor after it opens. I get a stupid window flash,
but its the best I can do...
