content: add newline to Printf call in flowcontrol

A missing \n doesn't matter when running the playground in the
browser, but apparently sometimes people copy the tour code snippets
in their editors; and anyway it's probably slightly nicer to be
consistent with the newlines.

Fixes golang/tour#642

A Tour of Go is an introduction to the Go programming language.

To install the tour from source, first set up a workspace and then run:

$ go get golang.org/x/tour

This will place a tour binary in your workspace's bin directory.

Unless otherwise noted, the go-tour source files are distributed under the BSD-style license found in the LICENSE file.

Contributions should follow the same procedure as for the Go project: https://golang.org/doc/contribute.html
