Subject: Fixed bug in the markdown reader:  HTML preceding a code block could
 cause it to be parsed as a paragraph.  (The problem is that the HTML parser
 used to eat all blank space after an HTML block, including the indentation of
 the code block.)  Resolves Issue #39. + In Text.Pandoc.Readers.HTML, removed
 parsing of following space   from rawHtmlBlock. + In
 Text.Pandoc.Readers.Markdown, modified rawHtmlBlocks so that   indentation is
 eaten *only* on the first line after the HTML   block.  This means that in  
 <div>        foo   <div>   the foo won't be treated as a code block, but in  
 <div>

      foo

  </div>
  it will.  This seems the right approach for least suprise.
