Remove untracked files that are unwanted after they are done being used. While the set of cases in this patch is certainly far from comprehensive, it was motivated by some work to see what the fallout would be if we were to make the removal of untracked files as a side effect of other commands into an error. Some cases were a bit more involved than the testcase changes included in this patch, but the ones included here represent the simple cases. While this patch is not that important since we are not changing the behavior of those other commands into an error in the near term, I thought these changes were useful anyway as an explicit documentation of the intent that these untracked files are no longer useful.
