PR #7637 followup: no need to print the set of removed files twice.

trivial r? for anyone who agrees with me.  :)

Given the choice between

 1. printing the set of files once on a single line,
 2. printing the set of files one per line, or 
 3. printing the set twice, once in each manner,

I originally chose (3.) since it seemed safest to be loud about this.  But now that I've used it for a bit, I think (1.) would suffice.
