For symmetry, I would prefer to make this 'if (column + 4 < editwincols...'
and 'return column - 4 - (column - 4) ...', but then (on a default 80-column
terminal) the cursor would jump unnecessarily and unexpectedly soon to the
next "chunk".  So the above is a compromise, between fixing the issue and
scrolling as late as possible.
