[TxMt] Minor update request to Python Bundle

[Steve Lianoglou]

Hi Allan,

It seems that empty lines in the doc-string are tripping up the doc- 
string fold itself.

Assume * are folding markers, then I get:

*    """First line of doc string.
      second line
*
      more...
      """"

It looks like we can combat that by putting an extra space as the  
"first" char of the blank line (at the appropriate indent level) ...  
so it's not a big deal.

Thanks for adding that into the language.
