Having said that, depending on how the strings are distributed, I have a
feeling that we might be better off having two variants:

	say >&2 "<message string>"
	gettext >&2 "<message string>"

The former would be

	say () {
		gettext >&2 "$1"; echo
	}

and minority of callers (they may be an empty set) that care about
trailing blank lines they output can include their own terminating LFs in
the message to be translated and call gettext directly, letting it output
the translation without stripping trailing LFs they (or their translation)
produce.
