title: body skipped with `send-email`?
body: <p>I created a patch for git like this:</p>
  
  <pre><code>git add .
  git commit -m "make slash-rules more readable"
  git format-patch master -1 HEAD
  </code></pre>
  
  <p>I then modified the file <code>0001-make-slash-rules-more-readable.patch</code> to something like this:</p>
  
  <pre><code>From de4a66a7f1fce4d231e3e70ca4ab2af3f8ed3cd3 Mon Sep 17 00:00:00 2001

  Subject: [PATCH] make slash-rules more readable
  
  gitignore.txt: make slash-rules more readable
  
  Make all paragraphs valid, even if they are not read
  in strict order. Make the paragraph for pattern without
  slash better understandable. Add paragraph for pattern 
  with slash. Be precise whenever a trailing slashes
  would make a difference. Add some examples.

  <p>I was then finally sending it to the mailing list with</p>
  
  <pre><code>git send-email -1 --to=git@vger.kernel.org
  </code></pre>
  
  <p>and got as a result:</p>
  
  <blockquote>
    <p>/tmp/Oq_BDD_ldq/0001-make-slash-rules-more-readable.patch</p>
  </blockquote>
  
  <p>Now the email was send to the list, however without the body. It starts with </p>

  <p>In addition <code>/tmp/Oq_BDD_ldq/0001-make-slash-rules-more-readable.patch</code> does not exists and <code>0001-make-slash-rules-more-readable.patch</code> is still inside the git folder, although it should have been removed after the mail was sent.</p>
  
  <p>Why is the file still in place (and not in <code>tmp/</code> folder) and why is the body missing in the mail? </p>
