1 From: Thorsten Haude <yoo@vranx.de>
2 From: Fredrik Corneliusson
3 Subject: Highlighted Cursorline
4
5 This is Thorsten Haude's patch, modified from Fredrik Corneliusson's patch
6 to provide a background color for the current line. You can find it here:

9 [ 683567 ] Highlighted Cursorline
10 cursorline.ajbj.2004-03-28.1.diff 2004-03-28 05:52
11
12 This coloring takes precedence over rangesets, syntax highlighting
13 backgrounds (if specified) and backlighting, but not over parenthesis match
14 highlighting nor selection.
15
16 It still requires work, for example for turning the cursorline highlighting
17 on and off through the GUI and through macros.
18
19 Thorsten has taken over this patch, integrating it with other functionality.
