title: Show hostname for local host with powerline
body: <p>I am using <a href="https://github.com/powerline/powerline/" rel="nofollow noreferrer">powerline</a> with bash, fish, and tmux. The hostname shows up when logging in to remote systems with SSH. But I want to also enable the hostname segment for local users. Here is how it looks on a remote system.</p>

  <p>Here is how it looks on as a local user. Note that I have <code>hostname</code> set on the local machine.</p>

  <p>The <code>tmux</code> theme works fine.</p>

  <p>I have tried editing the default theme by omitting the priority to always show the hostname segment disregarding the display width, and also edited the <code>&quot;only_if_ssh&quot;: false</code> argument. How can I enable showing the hostname in the shell prompt as well?</p>
