Why does inctxdirs() need to a be a function at all? It's a one-liner,
called once. Inline it! This *is* supposedly a performance
improvement, after all.

Oh yeah: why does inctx() need to be a function? I would inline it too.

And: does this really need to be done on the stable branch? Is it
actually fixing a bug, or just a minor performance tweak? That's
really not clear.
