A `git clone` will end with exit code 0 when `merged_entry()` returns a
positive value during a call of `unpack_trees()` to `traverse_trees()`.
The reason is that `unpack_trees()` will interpret a positive value not
to be an error.
The problem is, however, that `add_index_entry()` (which is called by
`merged_entry()` can report an error, and we really should fail the
entire clone in such a case.
Let's fix this problem, in preparation for a Windows-specific patch
disallowing `mkdir()` with directory names that contain a trailing space
(which is illegal on NTFS): we want `git clone` to abort when a path
cannot be checked out due to that condition.
