That was one of my questions as well. 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.

When will that spell checker for git messages be ready? ;)
