No, but I just tried it:
test=> \pset format wrappedOutput format is wrapped.test=> \pset columns 50Target width for "wrapped" format is
50.test=>explain analyze select * from pg_type, pg_language;                    QUERY
PLAN--------------------------------------------------Nested Loop  (cost=1.03..25.86 rows=807 width=66 5) (actual
time=0.037..4.528rows=807 loops=1)   ->  Seq Scan on pg_type  (cost=0.00..8.69 rows =269 width=555) (actual
time=0.018..0.377rows=2 69 loops=1)   ->  Materialize  (cost=1.03..1.06 rows=3 width =110) (actual time=0.001..0.005
rows=3loops=269 )         ->  Seq Scan on pg_language  (cost=0.00. .1.03 rows=3 width=110) (actual time=0.004..0.00 7
rows=3loops=1) Total runtime: 5.490 ms(5 rows)
 

Of course, running it on a 50-column display in 'aligned' mode isn't
going to look good either.
