Revert "repl,util: insert carriage returns in output"

This reverts commit fce4b981.

This was a breaking change and should have been marked semver-major.
The change that was made altered the output of util.format() and
util.inspect(). With how much those are used in the wild, this type of
change deserves more justification.
