I am mostly in favor of this change, as the calls to these three
functions are always preceded by increment of these fields, but it
is "mostly" exactly because the reverse is not true. Namely ...

... there still needs an increment in the context lines, not shown
in the patch, just after this "default:". I think the patch is OK
as the comment after this "default:" (also not shown in the patch)
makes it clear what is going on.
Thanks.
