title: in vim, how to append/insert text with argdo?
body: <p>There's the ":a" command, but that's multi-line, and argdo asks you for the text again for each file.</p>
  
  <p>The docs mention the global command (g/pat/command) that will use an alternative version of ":a" that is terminated by a newline instead of by "." on a line (you can include newlines by escaping them with "\").  But I couldn't get this to work.</p>
  
  <p>The only way I've seen is to first yank the text-to-be-added into a named register, then use:</p>
  
  <pre><code>:argdo put x                 " where x is the register
  </code></pre>
  
  <p>I'm hoping for something like</p>
  
  <pre><code>:argdo append myTextHere
  </code></pre>
