[Rd] as.character.Date() strips names in R 4.3.2 beta, bug?

[Andrew Piskorski]

In previous versions of R, as.character.Date() retained any names on
its input vector.  In R 4.3.2 beta, it removes names.  Is this change
intentional, or a bug?  (For what it's worth, I greatly dislike this
change, and hope it gets changed back.)
