Is "... is called" or something missing at the end of this sentence?

I actually doubt that the second line is expecting the right
behaviour in the first place.  As far as the top-level project is
concerned, "submod" is the name it wants, as there is nothing
underneath it.  Even if asked to recurse infinite levels, the caller
shouldn't be feeding paths like "submod/a/b/c" to
match_pathspec_depth() in the first place, no?
