Again, even if someone agreed with this convention, it does not address
the original problem of going SOUTH-east of the SOUTH Pole, which was
the original question arising from the original mistake.
But I would disagree with this convention. John Denker is absolutely
correct in observing latitude has nothing to do with it. As I wrote
before, you _could_ specify the line of longitude, 106° 50'14.38"E,
but that's not a compass point -- it's (half of) a great circle. The
fundamental problem is the coordinate system, and mixing a singular
point in that system with non-singular compass directions.
