Jon Gjengset f96e56c3a0 Avoid extra comma in vertical single-field struct patterns (#1403)
* Add (failing) test for #1397

* Fix for #1397

Specifically, we end up double-adding a trailing comma for single-member
struct patterns that are arranged vertically. One is added by write_list
(since such structs return true for needs_trailing_separator), and
another is added by the if in the old code.
