It's actually not a breakindent bug. The breakindent feature just makes
it more apparent. I can reproduce the issue on a plain 7.4 version.
Looking at the mercurial repository, that particular code is present
since the beginning of version 7. So I suspect, even the first Vim 7
also had the same problem.
The problem is, the display is correct, but the underlying data is
wrong.
Attached is a patch including a test.
Best,
Christian
