I have such structure of file:
a
<tab>b
c
Now if I move down line [a], it stay after libe [b] and have an indent, it's correct, but cursor stay on the first line, wich is [b] now, so, if I continue moving, I'll move line [b] now. Next indent level do same thing with [b] and other line.
It still present in daily build from 25.04.2016
The patch in #584 has been applied and it fixed this issue.
