It is curious that the original has two sources of hint_path (i.e.,
get_git_dir() is used as a fallback for get_git_work_tree()). Are
we certain that the check is at the right place? If we do not have
a repository, then both would fail by returning NULL, so it should
not matter if we add the new check before we check either or both,
or even after we checked both before dying.
I wonder if
const char *hint_path = get_git_work_tree();
if (!hint_path)
hint_path = get_git_dir();
if (hint_path)
die(_("%s: '%s' is outside repository at '%s'"),
elt, copyfrom, absolute_path(hint_path));
else
die(_("%s: '%s' is outside the directory tree"),
elt, copyfrom);
makes the intent of the code clearer. We want to hint the location
of the repository by computing hint_path, and if we can compute it,
we use it in the error message, but otherwise we don't add hint. And
we apply that conditional whether we have repository or not---what we
care about is the NULL-ness of the hint string we computed.

Excellent. This is a very good use of the GIT_CEILING_DIRECTORIES
facility.
