Yes they are unrelated, but the issue is the same... when and how to
trigger a line-width update/recalculation.

Actually on a windows resize the term-line width is not updated
either. So the new outputs after that assume the same window width. The
line-number-width is just another side of the same problem where the
line-width is not recalculated..

On window increase size the issue is not so annoying (it is not right,
but it works) but on window decrease size (or line-number-width
increase) it is worth because the lines adds a \ and break.

So a right fix maybe should recalculate the line-width more dynamically
(for example when inserting RET in term mode)

Does it makes sense?
