This is fine.

I find it helpful to clarify parsing challenges around such an use case.
It might occasionally be relevant if a line continuation indication
was accidentally forgotten or was intentionally omitted.

* Source code review should point such questionable places out, shouldn't it?

* How much does this implementation detail matter for the safe application
  of the semantic patch language?
