Speaking of 1e1ea69 (pull: implement skeletal builtin pull,
2015-06-14), one of the (numerous) things Paul Tan did which impressed
me was to formally measure test suite coverage of the commands he was
converting to C, and then improve coverage where it was lacking. That
approach increases confidence in the conversion far more than fallible
human reviews do.

Setting aside the top-down vs. bottom-up discussion, as a reviewer
(and user) I'd be far more interested in seeing you spend a good
initial chunk of your project emulating Paul's approach to measuring
and improving test coverage (though I don't know how your GSoC mentors
feel about that).
