Comment (by goldfire):

 Error2 seems to have the same mechanism (`:set +c` with a type
 application) as the original error, which is already in the testsuite. I
 personally don't think another test is warranted. Thanks for posting
 however -- if someone stumbles over this problem in the future, they will
 find your second case.
