Thanks for committing and sorry for the need to freshen up the
comments. I don't think I had ever opened buffile.c before and thus
wasn't sure if there isn't a better fix, so I didn't want to spend too
much time on it before somebody agreed it is the right fix.

Also, I was actually just trying to recover some data from a corrupted
database and this stopped me from it ;)
