How does this mesh with or formulated differently, if we're going to break POSIX compatibility, do we at least have sufficient evidence that all known systems cope with it?

(I vaguely remember assuming some issues in Libtool with passing things without a newline; alas, I never got to the bottom of that, and forgot about the details since.)
