This gives me:

./wt-status.h:94:12: error: array 'wt_status_diff_divider' assumed to have one element [-Werror]
cc1: all warnings being treated as errors

which is a bit unfortunate.

Regardless of that, from the API design standpoint, I think it may
be much better not to expose this particular implementation element
(i.e. the array) to the caller, but instead to export a helper
function that takes a pointer to a piece of memory and let callers
ask an "I have this line---is it the status cut mark?" question.
