She'er: Wife or Relative? (Trop)

In this week's פרשה we read כי אם לשארו הקרב אליו, לאמו ולאביו ולבנו ולבתו ולאחיו (Lev. 21:2). There is a מחלוקת whether שאר means wife or close relative. We know for sure that in certain places it has to mean relative. Otherwise שאר אמו (Lev. 13:18), for example, would not make sense (his mother's wife?). But in our פרשה it's not so clear.

Note the opposing views of Onkelos and "Targum Yonatan" (from ספר יין הטוב):

The widespread understanding follows Onkelos. See, for example, Rashi (ed. Silbermann/Rosenbaum): Dissenting views include Ibn Ezra (תורת חיים ed.) . . .

. . . and Shadal, I think (here for full text!; hattip Miss. Fred):
As I understand it, the trop in this פסוק agrees with "Targum Yonatan"/Ibn Ezra/Shadal. The presence of the אתנחתא that closes כי אם לשארו הקרב אליו seems to indicate that the phrase is the כלל, which is then followed by the פרט. Were the trop to agree with Rashi et al., I would have expected the אתנחתא (or זקף as the major trop?) to be found on ולאמו. This is based on the assumption that in a simple list composed of an even number of elements (as in our case), the major trop divides the list in half. From טעמי המקרא (sec. 22; also see פיסוק טעמים שבמקרא, pp. 122-23):
Finally, from Silbermann/Rosenbaum on whether Rashi really thought that שארו here refers to a wife (p. 184, n. 4):
