I don't like writing code that depends on particular
errno values, because I don't trust it to work cross-
platform.

Also it seems suboptimal to require people to use a
recipe like this to get the behaviour that is wanted
in the overwhelming majority of cases.

I don't see what would be so bad about adding a new
function for this. Think of it as correcting the mistake
of not making makedirs() behave this way from the
beginning.
