title: Pipe Vim buffer to stdout
body: <p>I'd like to use Vim in the middle of a pipe.  This <a href="https://stackoverflow.com/questions/6309587/call-up-an-editor-vim-from-a-python-script">existing post</a> looks like what I'd like to do, except I was hoping to do it without Python's help -- only with bash.  [It it helps, the environment is the bash shell in the Terminal IDE app on Android.]</p>
  
  <p>Please, I know how to pipe a buffer <em>through</em> a command from <em>inside</em> Vim.  That's great, but not what I want here.  I want to exit Vim and pass the active buffer to stdout.</p>
  
  <p>FWIW, I also know how to pass another command into Vim as input.  Again, that's not what I'm trying to get here.</p>
