I've never used any of the big files extensions so I can't say what would be
needed, and how automatic this could be. But I agree that it would be
reasonable to expect it to work if the big files are in some subdirectory.
With similar changes to perfarce I'd expect that subrepos could also be
populated, but again I'm unsure what would be needed.
This would be good to get some input from other users on too.
