[New-bugs-announce] [issue20752] Difflib should provide the option of overriding the SequenceMatcher

[Chris Rose]

New submission from Chris Rose:

It should be possible to provide subclasses or implementations of the SequenceMatcher interface to difflib's various methods that do formatting (for example, unified_diff/context_diff et al).

I've included a patch for it that satisfies my personal itch on the subject (attached). I'd like to have this reviewed for inclusion in 3.5.
