Hi,
Just a minor warning with documentation patch 
git apply ../v16-0003-Documentation-for-ALTER-TABLE-SPLIT-PARTITION-ME.patch
../v16-0003-Documentation-for-ALTER-TABLE-SPLIT-PARTITION-ME.patch:54: trailing whitespace.
      One of the new partitions <replaceable class="parameter">partition_name1</replaceable>, 
warning: 1 ligne a ajouté des erreurs d'espace.
(perhaps due to my Ubuntu 22.04.2 french install)
Everything else is ok.

Thanks a lot for your work
Stéphane
