Is there a way to get emacs to show something like the squiggles that vi
shows under the last line of text in the file? The ideal behavior is Vim
under GUI, which shows that but also *just slightly* changes the background
color with the squiggles. This is not a huge deal but I find it comforting
to know exact information about the file, including how many line
terminations I have in there, and this is an instantaneous way of telling
that.
