It looks like after this patch, if you change lines in another buffer
some marks in the current window will be moved. Especially the
jumplist, perhaps setting cmdmod.lockmarks would help. The '< and '>
marks are probably moved. Manual folds might be moved. There may also
be redrawing problems.
This needs a test in src/testdir. And documentation, of course.
I'm very careful with including something like this. Currently there is
no code that changes another buffer. It could break more than you
expect.

The primary purpose of the DATA statement is to give names to constants;
instead of referring to pi as 3.141592653589793 at every appearance, the
variable PI can be given that value with a DATA statement and used instead
of the longer form of the constant. This also simplifies modifying the
program, should the value of pi change.
