Should read_tree_recursive be propagating a -1 and merge_trees be checking for that and bail when the call to get_files_dirs return is < 0? I made a commit with this change and ran the tests and they all still passed so either this return really doesn't matter or there are not sufficient tests covering it. I went with this change because it was not changing any of the current functionality and if we find a case where it matters that read_tree_recursive fails due to bad tree or something else we can address it then. > > I'm tempted to say that we should probably die() when > read_tree_recursive fails.
