Yeah, chopping off s and e looks like it will work but probably isn't
the ideal solution.  That would effectively prevent islands from
wrapping, which someone says might be intentional in the thread you
reference.

The current situation does wrap, I think.  If an island flows off the
edge of the screen the data just overflows.  This effectively wraps the
X value while increasing the Y value by 1.  But, I haven't looked at
this too deeply so I could be wrong.
