OK, I didn't know that. (In fact, I checked my own lprngtool-generated
printcap, and it didn't seem to contain anything harmful. Yes, one
datapoint, I know).

That was never revealed in the package description, was it?

Henning Makholm       "It was intended to compile from some approximation to
                 the M-notation, but the M-notation was never fully defined,
                because representing LISP functions by LISP lists became the
 dominant programming language when the interpreter later became available."
