I disagree, I think consistency is desirable in this case.

I agree it works, but \\$3 isn't empty, it only compares as empty
against another string.  ;-)

    $ cat endbrace.tr
    .de t3
    .tm \\$1/\\$3.
    .if '\\$3'' .tm empty
    .if !'\\$3'' .tm not-empty
    ..
    .t3 1 - x
    .t3 2 -
    .if t \{
    .t3 3 - \}
    .t3 3 - \}
    $
    $ groff -w all endbrace.tr >/dev/null
    1/x.
    not-empty
    2/.
    empty
    3/\}.
    empty
    3/\}.
    empty
    $

Cheers, Ralph.
