Hello, I vaguely recall having posted this same concern previously. I
just noticed that all @ruser links from learning manual are broken in
all translations.
They produce links in the form
http://lilypond.org/doc/v2.21/Documentation/notation/note-names-in-other-languages
i.e. directly to a file with the name of @unnumberedsubsubsec, which we
don't generate. They should be in the form
http://lilypond.org/doc/v2.21/Documentation/notation/writing-pitches#note-names-in-other-languages
instead, i.e. @subsection # @unnumberedsubsubsec
English manuals have correct links.
