$ should not be used in regexs unless you really want to allow a trailing "\n"; probably not the case here.

Well, since all whitespace has been normalized to single space (and leading and trailing whitespace has been removed), $ works as well as anything else here.

    On the contrary, since it is impossible for there to be a trailing \n here, using $ instead of \z is misleading and wrong. It's just as incorrect as needlessly ending an unanchored regex with .*.
