Solution: When adding an error list entry pass the buffer number if possible.

You were lucky. We lived for three months in a brown paper bag in a
septic tank. We used to have to get up at six o'clock in the morning,
clean the bag, eat a crust of stale bread, go to work down mill for
fourteen hours a day week in-week out. When we got home, our Dad
would thrash us to sleep with his belt!
