Can we make it not important? That is, if the type is always
explicitly a directory, treat it as such using the usual file name
joining logic.

Alternatively, and perhaps better, don't introduce a second argument.
Just pass the full file path in the first argument, and have asset
mapping always work it out in the right way.
