In note 33 for the 1987 JMT article, I mention the incomplete line ^5-^7-^8. A "textbook" example of this "primitive Urlinie" in tandem with a proto-background ^3/^5 may be found in the ninth number of Schubert's Ecossaisen, D781. See the circled notes in bar 1 -- the pairing is obvious through the first strain; I have traced the voices in the score as they trade positions in the second strain.
The “verlorener Bruder” Trio, D610 (a trio without a menuet), neatly frames ^5 in its basic idea and transposed repetition (bars 1-4), then focuses on movement upward to ^8 in the continuation. In the shortened reprise (the final four bars), there is a bit of a "lost soul" sort of posthorn touch, and the voices are firmly set against one another at the last -- see the boxed notes.
In note 33, I mentioned Schubert, Ländler, D. 681, nos. 1 & 2 (perhaps as ^5-(^8)-^7-^8). Unfortunately, I don't have easy access to these at present. It is perhaps worth noting that these pieces would be nos. 5 & 6 in the complete 12 Ländler, D. 681 (from 1815), but the first four have been lost.
