I thought you were talking about problems like "that that" typos,
but on looking at the file, what this is actually complaining
about is any duplicated code segments anywhere.  I do not find
this helpful.  Refactoring to the point that dozen-line code
stanzas never appear more than once would be incredibly invasive,
likely very bad for performance, and I don't think it'd improve
readability either.

Commit triggers are NOT the place for heuristics about code quality,
even if they're well-considered heuristics.
