Hey Taylor,

This was happening on a (much) more massive repository; I simply tried to dumb down the example.

The original folder did had a folder structure 3 levels deep. Unfortunately, I don't remember if the leaves were files (or directories themselves). However, since I "replicated" it, I went ahead and cleaned up my main repo (sigh).

Thank you for reminding me of the empty-tree case :-)

(Reply-all missed the list)
