bug#21386: 25.0.50; Make visual rectangular selection look better

[Mark Karpov]

There is a cool new feature in Emacs 25: visual support for rectangular
selection. However, I would like to set its width to one pixel when it's
“logical” width is zero columns of text. By default it's a bit too
bold. Is it possible?

Also, it would be cool if it didn't “shift” text on the right side of
the selection when its width is zero.
