Hm.. I took that to mean "changes on the same line". I now realize
this interpretation has been an overly strict interpretation.

Yes, that's how I understand it as well. Your example seems fine
(except that it does not make much sense to merge with an ancestor).

I'm not sure if git also works line by line (as does monotone).
However, IIRC kdiff3 uses some finer grained comparison, so it can
even merge unrelated change on the same line, i.e.:

ancestor: aaa bbb
left:     axa bbb  (modified a -> x)
right:    aaa byb  (modified b -> y)
merge:    axa byb  (contains both modifications)
