Thank you Christian!

So what I have:
Compiled and tested on Windows 7
MSVC 2008 Express, Windows SDK 7.0

Compiled with patch applied.

1. Tested with:
set leftmargin=1 (2,3....)

Works correct and shows correct colors, with and without line wrapping.
This is so good! Unindented text looks now sooo much better.
Even 1 char margin makes a big difference.
I make line numbers more contrast and this looks good
with any colors.

One problem though: there is some lag when moving cursor through
the document. E.g. press and hold the down arrow key for
several seconds - after releasing the key, cursor keeps moving
several lines more.
In the non-patched version I cannot notice this lag at all.
This gets more severe with wrap on.


2. Tested with
set leftmargin=0

- If wrap is on: scrolling up breaks rendering
- Selection does not highlight the seletion area

So with 0 margin something is going wrong.

So it is, I've played with it several hours and
have not noticed other things yet.

Mikhail
