[issue21827] textwrap.dedent() fails when largest common whitespace is a substring of smallest leading whitespace

R. David Murray added the comment: It's one of the PEPs (I forget which one). We only apply non-security fixes to the most recent non-development branch...except that for now we also apply bug fixes to 2.7. So, 2.7, 3.5, and 3.6 are the targets for this issue. -- versions: -Python

John Mark Vandenberg added the comment: Not surprising also occurs on Python 3.2, 3.3, & 3.6. I'm not sure whether fixes like this are suitable to be merged into 3.2/3.3.(is there a document describing this?) -- nosy: +John.Mark.Vandenberg versions: +Python 3.2, Python 3.3, Python 3.6
