I suppose... though I think that if others agree, I'd rather update the
documentation instead of introduce some inconsistency.

Yes, there's an argument to be made that if we're encouraging users to
go from '--get-color' -> '--type=color', that the two should behave the
same, but I don't think the cost we pay for behavioral equivalence
between the two is worth inconsistency among '--type=color' and all the
rest.

As you indicate, I think that this option is one we should _not_ do. In
the interpolation example you shared earlier in the thread, script
writers most likely want and expect a trailing LF after each invocation
of 'git config'.

I'd argue that this case is more common than not wanting a LF when
interpolating with `--type=color`, so I agree it seems the tradeoff here
is not a good one.

To restate my response to (1), I think that the documentation update in
isolation makes the most sense here. I, too, was surprised in the same
way that Peff was when we stumbled upon this, but I think that
ultimately the consistency is most favorable.

Thanks all for your discussion and feedback.
