I have been trying to create Sigil files with no "sgc-" CSS entries.
The following style sheet entry always shows up but no where in the code can I find it used.
	Code:
	  <style type="text/css">
/*<![CDATA[*/
  p.sgc-1 {text-align: center}
  /*]]>*/
  </style>
 Is it just an artifact or have I missed something?
