I think it's just that the pattern to find "start of new function" is
confused by the "__visible" or something.
Don't rely too much on the function names in the diff headers. They
can be confused by labels, or just by other things. I think it ends up
being "does the line start with alphabetic character" that is the
heuristic for "this is a function header".
