title: Bold italic in ReStructuredText
body: <p>I'm writing some documentation using ReStructuredText (ReST) format for the later web-page generation using Sphinx, and I cannot find a way to write some "bold italic" text. </p>
  
  <p>There are markers for the so-called 'emphasis' (<em>italic</em>) and 'strong emphasis' (<strong>bold</strong>) text. They are <code>*italic text*</code> and <code>**bold text**</code> respectively. I also read in some documentation on this format that these formatting markers cannot be simply "nested". I.e. the <code>***text***</code> (or <code>** *text* **</code>) does not produce the <strong><em>bold italic</em></strong> text.</p>
  
  <p>Still there probably should be some way to produce a text emphasized both with bold and italic markers, since it is a widespread practice to mark pieces of text that way.</p>
