Freeze with table not preceded by an empty line

[jpfleury]

1. Create a file n.py with the following content:

   import markdown
   
   text = """
   Lorem ipsum
   Lorem ipsum dolor sit amet inceptos | Lorem ipsum | Lorem ipsum
   ----------------------------------- | :---------: | :---------:
   Lorem ipsum                         | Lorem ipsum | Lorem ipsum
   """
   
   print markdown.markdown(text, extensions=['extra'])
   

2. Run the file:

   $ python n.py
   

Actual result: Python-Markdown freezes. If we interrupt the process, we have the following output:

$ python n.py 
^CTraceback (most recent call last):
  File "n.py", line 10, in <module>
    print markdown.markdown(text, extensions=['extra'])
  File "/home/nom/.local/lib/python2.7/site-packages/markdown/__init__.py", line 386, in markdown
    return md.convert(text)
  File "/home/nom/.local/lib/python2.7/site-packages/markdown/__init__.py", line 283, in convert
    root = self.parser.parseDocument(self.lines).getroot()
  File "/home/nom/.local/lib/python2.7/site-packages/markdown/blockparser.py", line 62, in parseDocument
    self.parseChunk(self.root, '\n'.join(lines))
  File "/home/nom/.local/lib/python2.7/site-packages/markdown/blockparser.py", line 77, in parseChunk
    self.parseBlocks(parent, text.split('\n\n'))
  File "/home/nom/.local/lib/python2.7/site-packages/markdown/blockparser.py", line 93, in parseBlocks
    if processor.test(parent, blocks[0]):
  File "/home/nom/.local/lib/python2.7/site-packages/markdown/blockprocessors.py", line 470, in test
    return bool(self.SEARCH_RE.search(block))
KeyboardInterrupt
$

Expected result: no freeze.

More information:

• The following code doesn't make Python-Markdown to freeze:

  import markdown
  
  text = """
  Lorem ipsum
  
  Lorem ipsum dolor sit amet inceptos | Lorem ipsum | Lorem ipsum
  ----------------------------------- | :---------: | :---------:
  Lorem ipsum                         | Lorem ipsum | Lorem ipsum
  """
  
  print markdown.markdown(text, extensions=['extra'])
  

• Tested with waylan-Python-Markdown-2.1.0.beta-0-ge8cdb0b.zip.

This is indeed related to #47. In fact, the input is an invalid table, so it is seen the same as if the table extension was not being used. Closing this as a duplicate.
