Hi Joe,

Thanks for the patch!!  If I remove the above 'die' line I can pass in a
file or a dir.  Otherwise the 'die' line prevents a 'file' from being used.

Not sure if that is important for this patch or not.

We have an internal use case of multiple MAINTAINER files, some folks have
more rights to patches than others so they are not allowed to be cc'd (think
embargoed stuff).

So the 'file' usage would be useful for us.   But if you are against it, we can
easily patch it out on our end.

Prarit,

I believe this patch still does what we want (and handles your pci example).

Cheers,
Don
