Ouch, that was unexpected.
The manual for my version only includes four mentions if the noweb-ref
header argument. Is it becoming deprecated?
What does "apparently don't need" actually mean? That is, when should I use
the name, and when the header argument? What can the header argument do
that the name cannot?
