Thanks for the images, now it's clearly seen that the problem is that
currently line numbers are displayed as part of the buffer text that
is confusing - you can't edit these numbers.  Whereas like fringes
are displayed with a darker background, it makes sense to display
line numbers with the same darker background to indicate these
numbers are not part of the buffer text.  So you patch fixes
the real problem.
