Sorry, my mistake:
\relative c' { \stemDown c8[ d] \stemUp e[ e'] }

Hello, Jacques Menu!
Since you did not specify
the time signature, lilypond chose the default one — 4/4.
In this signature, lilypond groups 1/8-notes by four. You
can explicitly override it:
\relative c'[ { \stemDown
c8] d \stemUp e[ e'] }
For additional information
you can read the documentation: http://lilypond.org/doc/v2.22/Documentation/notation/displaying-rhythms
