   This is how it works with long wxPython widget strings. I did not make the
connection to enclosing characters.

   Unless the string is delineated with single quotes (as in a content list
for a drop-down picklist control). :-)

   I'm used to seeing (and writing) newlines in bash scripts and other text
so now I know python recognizes it I can use this solution.

Much appreciated,
