As I wrote originally, I'm trying to highlight the output of a
static analysis tool. It happens to be Klocwork's kwcheck program.
In the plugin that runs the analysis and captures the output into a
buffer, I have
setlocal filetype=klocwork
(Yes, I know 'filetype' doesn't have to be set with :setlocal, but
it looks better along with all the other :setlocal settings.)
Then I also have a klocwork.vim file in my local syntax directory
that has in it
syn sync fromstart
along with the ":syn match ...", etc., lines. That was one of the
first things I tried when I discovered the problem, but it doesn't
help.
It seems to be a bug in Vim's handling of these two factors when
present together:
* A syn match pattern containing "\zs\n";
* The redrawing that occurs when scrolling backwards by lines.
Regards,
Gary
