Setting a global hooks path causes "Cowardly refusing to install" everywhere

I recently setup a global spell checking commit hook that lives in

git config --global core.hooksPath ~/dotfiles/gitHooks

Just noticed that due to this, attempting pre-commit install now fails with

[ERROR] Cowardly refusing to install hooks with `core.hooksPath` set.

in every repo.

Is there actually a reason to fail in the presence of global hooks? Local hooks are still executed unless they’re being shadowed by a global hook of the same name, i.e. a global commit-msg hook would prevent a local commit-msg hook from running. In that case, it’s the user’s responsibility to make sure the global hook calls the local one if so desired.

If there is indeed no reason not to let global and local hooks coincide, fixing this might be as easy as modifying

def has_core_hookpaths_set():
-    _, out, _ = cmd_output_b('git', 'config', 'core.hooksPath', retcode=None)
+    _, out, _ = cmd_output_b('git', 'config', '--local', 'core.hooksPath', retcode=None)
    return bool(out.strip())

Happy to submit a PR for that.
