New submission from Myles Dear: The textwrap.dedent function does not work when the string to dedent itself contains embedded strings that contain newline characters.
https://docs.python.org/3.4/library/textwrap.html?highlight=dedent#textwrap.dedent states that this function "can be used to make triple-quoted strings line up with the left edge of the display". It just so happens that my triple-quoted string itself contains a single-quoted string with newline characters. I would have expected textwrap.dedent to ignore these newline characters inside single or double quoted strings contained in the larger triple-quoted string. The semantics of this bug may be slightly different than https://bugs.python.org/issue19479 "textwrap.dedent doesn't work properly with strings containing CRLF", so I'm raising a new issue. I am seeing this in a module I'm writing that emits synthetic python code that is subsequently passed back into the interpreter via "exec".
