title: Backspace deletes prompt in terminal
body: <p>In the following scenario, my bash prompt looks like this:</p>
  
  <pre><code>Username@Hostname ~ $
  </code></pre>
  
  <p>If I type any number of characters, and then press the delete button one-too-many times, it will clear the entire line. For example:</p>
  
  <pre><code>Username@Hostname ~ $ ls
  </code></pre>
  
  <p>then I delete <code>s</code></p>
  
  <pre><code>Username@Hostname ~ $ l
  </code></pre>
  
  <p>then I delete <code>l</code></p>
  
  <pre><code>|
  </code></pre>
  
  <p>I'm then left with my cursor without any sort of prompt. I can type up commands normally and everything seems to function fine--but why does the prompt disappear? Is there a way to stop this behavior?</p>
