It was loaded, because the adjusted_pathspec algorithm stripped the
trailing slash and then everything until the next slash. That's
overkill except when the trailing slash had to be stripped.
I'll make the adjusted_pathspec algorithm more restrictive, so the last
trailing slash is no longer stripped. If a pathspec contains a trailing
slash I'll load the whole index, as you suggested.
