Actually, no, it is not a requirement any more that
GNULIB_TOOL_IMPL=sh+py works in all cases.
This strict "same output" check was useful before we switched
to the Python implementation by default, and in the few weeks
afterwards.

It's OK now to make small changes to the output of gnulib-tool.py,
and change the unit tests accordingly.(*) This will make the unit
tests fail with GNULIB_TOOL_IMPL=sh, but it is no longer important
since the shell implementation is only maintained for a diminishing
set of users.

(*) Of course the changes to the expected outcome of the unit tests
must be carefully reviewed!
