Hi! I did the following:
- cloned http://git.savannah.gnu.org/cgit/emacs.git
at commit 19428947aaf2c68ad735a65bdc02d0523b5d15ae
(Mon Jun 16 12:49:09 2014 +0400)
- applied the same changes as before, additionally taking into account
Stephen's observations about left scroll-bar and a compilation error
- checked that the modified ruler-mode.el compiles with no errors
and no warnings
- rebuilt the patch with "git format-patch 19428947aaf2c68ad735a65bdc02d0523b5d15ae"
The new tentative patch is attached here below:
