This generates a lot of false positives, like "that that" which is
grammatically fine.  And fails to ignore entries separated by multiple
lines, but the concept is cool.  Respect for building that.

I looked at what the command above produces, and it seems to me that you
have spotted all the spots which are problematic, so committed after
applying a proper indentation, which was incorrect in two places.
