title: sink() function used with Ctrl-Enter in ESS keeps printing working directory in output file
body: <p>I am seeing a strange behavior with sink() in R, when used with ESS in Emacs.</p>
  <p>If I sink output, by using</p>
  <pre><code>sink(&quot;file-name&quot;)
  </code></pre>
  <p>and I then feed lines to my R session from another buffer by using Ctrl-Enter, this seems to cause the current working directory to pop up in the sink destination file. In other words, it's as if, when I hit Ctrl-Enter,  someone had executed getwd().</p>
  <p>This seems to be new behavior, as I don't recall encountering this in the past. Any ideas how to stop this? Executing sink() with type=&quot;output&quot; has no effect.</p>
