2699 The worst case is usually No. 2. It means that (aside from
2700 potential need for getting the gap out of the way), there also
2701 needs to be a shifting of the text between the two regions. So
2702 if they are spread far apart, we are that much slower... sigh. */
2704 /* It must be pointed out that the really studly thing to do would
2705 be not to move the gap at all, but to leave it in place and work
2706 around it if necessary. This would be extremely efficient,
2707 especially considering that people are likely to do
2708 transpositions near where they are working interactively, which
2709 is exactly where the gap would be found. However, such code
2710 would be much harder to write and to read. So, if you are
2711 reading this comment and are feeling squirrely, by all means have
2712 a go! I just didn't feel like doing it, so I will simply move
2713 the gap the minimum distance to get it out of the way, and then
