Thanks for doing that, again.

I just update m4.git to the latest gnulib, and it failed to compile
because it was expecting the old "pipe.h".  This patch mirrors what
is done by the getdate transition module, by keeping the old name
around until such time as packages have swapped to the new module.

Therefore, I don't think we're quite at the point of removing the pipe
module, yet.

> In a third step, later again, you can then rename 'pipe-posix' to 'pipe'.

But yes, these three steps do sound appropriate.
