This adds a test for `head()` on the right-hand side of a pipe. This also removes the try-catch surrounding `fs.openSync()`, because it was unreachable code. `fs.existsSync()` guarantees that the file exists, and `fs.openSync()` only throws if the file does not exist, according to official documentation. Fixes #671
