title: Zsh backslash madness?
body: <p>Zsh seems to do some weird backslashing when you try to <code>echo</code> a bunch of backslashes. I cannot seem to figure out a very clear pattern to this. Any reasons for this madness? Of course, if I actually wanted to use backslashes properly, then I'd use proper quoting etc, but why does this happen in the first place?</p>
  
  <p>Here's a small example to show the same:</p>
  
  <pre><code>$ echo \\
  \
  $ echo \\ \\
  \ \
  $ echo \\ \\ \\
  \ \ \
  $ echo \\ \\ \\ \\
  \ \ \ \
  $ echo \\\\ \\ \\
  \ \ \
  $ echo \\\\\\ \\
  \\ \
  $ echo \\\\\\\\
  \\
  </code></pre>
