Oops my bad.  I should have expected that Emacs commands are invisible
unless the right Emacs mode is used.  Thank you for clarifying and
presenting as a patch.

Oh hmm doc/guix-cookbook.de.texi is not checked in, so even `make
as-derivation` should have worked ...

This got nothing to do with stray .de.texi files.  Apparently it is
because the menu entries lack menu descriptions (which should be
optional according to `info texinfo').

The attached patch on top of your patch helps ...

Either we add optional descriptions everywhere or not update menu
entries without description or change how po4a translates the menu
entries in po4a source file lib/Locale/Po4a/Texinfo.pm in
translate_buffer_menuentry, to make po4a translate when there is no
description.  I don’t plan to do that though.

Regards,
Florian
