without the patch, the error isn't correct either:

I don't offhand see what's wrong with the diagnostic, as the PATTERNS
operand is documented to be one that "contains one or more patterns
separated by newlines".
doing the one that compiles
every line independently and that will catch that problem wouldn't be
that difficult, but I would rather do it as a follow up, and is
definitely going to be bigger.
Yes, that sounds better. Please keep the followup in this thread. Also,
I hope you'd be willing to assign copyright to the FSF as I assume these
changes will be nontrivial. I will send you paperwork info about that
via separate mail offlist.
