Disclaimer: I'm using Emacs Prelude, but I don't think this is a problem of that specific distribution.
Some time ago I discovered that pressing
C-S-up with no selection just swaps the line above the current one and current one. The point stays on lower line and doesn't follow the moved line. It was not the case earlier, although I can't tell what broke it (maybe some update). The both sequences are bound to
move-text-down still works properly - moving unselected line and point both down.
I didn't modify my
transient-mark-mode doesn't help either. I use
move-text-20140307.1644 and GNU Emacs 24.4.1 which I built from sources myself.
How can I debug and fix the problem?..
