title: zsh alias expansion
body: <p>Is it possible to configure zsh to expand global aliases during tab completion?  For example, I have the common aliases:</p>
  
  <pre><code>alias -g '...'='../..'
  alias -g '....'='../../..'
  </code></pre>
  
  <p>but when I type, for example, <code>cd .../some&lt;tab&gt;</code> it won't expand to <code>cd .../something</code> or <code>cd ../../something</code>.  Consequently, I frequently won't use these handy aliases because they are incompatible with tab completion.</p>
