Oops; your patch is fine (see nit-pick) for core-updates; but as you
noticed, on master we need to add an indirection to avoid rebuilds.
What about something like

--8<---------------cut here---------------start------------->8---
diff --git a/gnu/packages/commencement.scm b/gnu/packages/commencement.scm
index aa30e3fa18..48f9a47c6b 100644

Thanks for catching this!

    ^

This is the closing parenthesis of a string-append that has only this
one big string; what about removing that string-append altogether?
