A quote without any indication of it being a quote, starting immediately
after a non-quoted note?  Isn't that kind of a fake example?

Now it is my turn not to be able to figure out the meaning.  "offset" in
the meaning of adjusted, or relocated?

"non-musical" is definitely a good term to be used in the documentation.
It captures an important concept.  But there is also a musical
component: \fake) is the entrance of a wormhole ultimately leading to
some musical ), and \fake( is the exit from a wormhole that ultimately
had some musical ( before it.  So they are a binding promise of real
musical content at a different visual location, restoring the spanner
symmetry broken by the non-linear visual arrangement.

What's a term for the other side of a wormhole?

\surrogate would also reflect one part of the concept, but that word is
so artificial...  I'd prefer some term that would grow into a natural
concept to a degree where people would prefer using it extensively over
having an automatism that leads to source code with unmatched
delimiters.

Like electrical engineers preferring to add an imaginary component to
differential equations in order to have something much nicer to work
with, even if they are going to throw the imaginary component away after
they have finished solving the equation.
