fwiw, there is this comment in the code:
* Note that this code does not currently look for all possible
redundant cases
* and either ignore or stop with warning. The create might fail
later when
* names for indices turn out to be duplicated, or a user might have
specified
* extra useless indices which might hurt performance. - thomas

But I should (probably) be able to fix this particular case.
