OK. If you start to go into this direction, it is time for me to
implement the GNULIB_TOOL_IMPL=sh+py option. Done through the patch below.

But in the current state, it fails for nearly every command. There's
no hope that you can expect identical results from the two implementations
as long as there are still items in the TODO list.

You can keep such a file locally.
