2056 1. Adjacent (contiguous) regions, or separate but equal regions
2057 (no, really equal, in this case!), or
2058 2. Separate regions of unequal size.
2060 The worst case is usually No. 2. It means that (aside from
2061 potential need for getting the gap out of the way), there also
2062 needs to be a shifting of the text between the two regions. So
2063 if they are spread far apart, we are that much slower... sigh. */
2065 /* It must be pointed out that the really studly thing to do would
2066 be not to move the gap at all, but to leave it in place and work
2067 around it if necessary. This would be extremely efficient,
2068 especially considering that people are likely to do
2069 transpositions near where they are working interactively, which
2070 is exactly where the gap would be found. However, such code
2071 would be much harder to write and to read. So, if you are
2072 reading this comment and are feeling squirrely, by all means have
2073 a go! I just didn't feel like doing it, so I will simply move
2074 the gap the minimum distance to get it out of the way, and then
