As you may have guessed, I'm using source quite heavily for finding
things I suspect may exist. \text_put_sp: is not in the "documentation"
part of source3, so doesn't show up by default. Looking at l3messages,
it seems there is quite a bit that doesn't make it to the "use" part. I
shall read the implementation properly on this.
