find-file-not-found-hooks and interactive prompting...

I have been using a package called `ff-paths' for a little while now and it's /very/ nice for what it does.[1] It adds a hook to the `find-file-not-found-hooks' that uses locate and a couple of other tricks to try and find the file on the file system when it's missing. This works really well for interactive use where it pops up a buffer asking which file you wanted or if you meant to create a new file by that name. The problem I have is that it /also/ does this for things like the PCL-CVS mode 'ignore file' functionality. So, doing that, PCL-CVS calls find-file and I get a popup asking which '.cvsignore' I meant... This is undesirable when the find-file was not called interactively, as was the case for the PCL-CVS mode thing. I can't see any reliable way to determine if the call to `find-file' was interactive, though, by the time we hit the `find-file-not-found-hooks'. So, have I missed something or is there a better way of achieving this?
