I've removed the comment and fully qualified the two other calls to
make_unique in the same function in r208219. Two questions:

1. I guess we don't have buildbots with the right version of MSVC to hit
   this?  I didn't get any email.

2. Why wasn't the zero argument call to make_unique ambiguous?
