Thanks for the fix. The patch overall looks good to me. A couple of small comments:

1
```
     /*
      * Calculate available width for data in wrapped mode
      */
-    if (cont->opt->format == PRINT_WRAPPED)
+    if (cont->opt->format == PRINT_WRAPPED || cont->opt->format == PRINT_ALIGNED)
```

Since the condition has been updated, I think the comment above should be adjusted as well.

2
```
+-- the output in expanded mode is shorter than header
+\pset border 2
+\pset expanded on
+create table psql_short_tab(a int, b int);
+insert into psql_short_tab values(10,20),(30,40);
+\pset format aligned
+select * from psql_short_tab;
+\pset format wrapped
+select * from psql_short_tab;
+drop table psql_short_tab;
+
```

After this test, does it make sense to turn expanded mode off explicitly, in case it affects following tests? Today the
nexttest happens to reset it, but maybe tomorrow a new test gets added before that point.
