bug#12012: feature request: scrollbar in fringe |

Hello all,
yascroll.el ( https://github.com/m2ym/yascroll-el ) is an awesome emacs package
that makes use of the right fringe to draw a scrollbar.
This works great, with just one issue. It is not possible to draw below the end
of the buffer. So when the buffer ends in the middle of the screen, it is not
possible to draw the scrollbar at the bottom of the window.
Now we have noticed, 'indicate-empty-lines is able to draw empty line markers
below the end of the buffer. So I've asked the development mailing list if it
is possible to do this from elisp:
http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00148.html
So that's why I am issuing a feature request. There are 2 possible ways to fix
this:
- implement a scrollbar in the fringe completely in c code
- allow elisp to draw beyond the limits of a buffer
I did have a quick look at the c code used to indicate-empty-lines, but it
didn't make a lot sense to me.
Maybe somebody is willing to implement the fringe scrollbar, or able to point
me out how to accomplish this in c code?
Regards,
Toon
