s/correctly,/correctly (a brief desription of why),/
would be nicer. The description might be
(after a merge, it is OK for the result to be identical to HEAD,
which usually causes a "nothing to commit" error)
or something like that.

OK. Sounds like a good clean-up.

Your description so far marked function names with trailing ();
let's do so consistently for wt_status_get_state(), too.

"should be but isn't" because...? I am wondering if it is better to
leave _all_ constifying to a later effort, if we are leaving some of
them behind anyway. It would be better only if it will make this
patch easier to read if we did so.
Also you did s/commitable/committable/ everywhere, which was
somewhat distracting. It would have been nicer to follow if that
were a separate preparatory clean-up patch.
