"finalize" is indeed not the right name. I made a separate function to
avoid too much code duplication between status and commit, and looked
for a name comlementary to "prepare" for a function that is ran later to
fill-in some fields.

(Yes. This includes the advice section, so I need it for
advice_status_hints)

That is clean, but a bit long and it is essentially duplicated between
status and commit. I went another way: put all the similar code in a
common function status_init_config:
static void status_init_config(struct wt_status *s, config_fn_t fn)
{
wt_status_prepare(s);
gitmodules_config();
git_config(git_status_config, s);
determine_whence(s);
s->hints = advice_status_hints; /* must come after git_config() */
}
We could split the git_config call, but that would not bring much
benefit IMHO. In any case, it can be done very simply on top of my patch
if needed later, as there is now only one call site for git_config.
