Sorry, but what problem are you trying to solve?  The output from

    $ gettext "foobar"

may have 0, 1 or more LF at the end, but wouldn't 

    echo >&2 "$(gettext "foobar")"

terminate with a single LF in any case?

Ahh, perhaps I was the one who said something stupid like:

	echo >&2 "$(cmd)"

should be equivalent to

	cmd >&2

which is not the case when output from cmd does not end with a single LF
(i.e. either an incomplete line, or with trailing blank lines).

Sorry, if that is what you are trying to address, please let me take that
back.
