The basic difference is that vile stores each line as a chunk,
while emacs and vim store the file as a couple of chunks.

I don't recall what elvis and nvi do (elvis used to use a third
scheme, which is more like the traditional vi, that is managing
text in pages which were written to disk).

If you google around for "buffer gap", you'll find some discussion.


(There's a long story there, but short of rewriting the program,
I don't see how to change it).
