If we don't find holes in our hole rb tree we'll just assume there's a
gap from 0 to the length of the file and print that out. But this
simply isn't correct, we could have a gap between the last extent and
the isize, or 0 and the start of the first extent. Fix the error
message to tell us exactly where the hole is.
