And I assume this, by itself, doesn't cause any problem to make,
correct?

I think we should go this way, yes.  After all, albeit the trailing
'\' in the .Po file looks strange, it's not causing any problem in
practice, and it's only our hacky editing of said .Po that is
triggering the failure.  So let's fix this editing and live happy.

Any patch that does so (and adds brief a comment explaining why we
need the extra 'echo') can be considered pre-approved.

Thanks,
  Stefano
