Exactly. The changed files are used only to generate PDF
documentation for one of my packages (ttfautohint), which heavily uses

distribution in a generic way. As soon as the corresponding changes
are applied upstream, I will use the upstream packages. However, I
can't estimate in advance when updated packages appear...
