[Message part 1 (text/plain, inline)]

Correction from my side, the last problem seems to actually be independent
of the fix, I reproduced it with vanilla emacs from vcs, no hl-line-mode,
emacs ran with --no-init, without any .Xresources etc., just:

(setq-default left-margin-width 1)

open a new buffer, select a few lines, and you get this:
