Oh, I haven't noticed that behavior in Emacs before. So, if I haven't pushed a mark before, then Emacs will automatically push it (while mg pushes it in all cases). Also that C-u prefix part is not true (I made a check, also thank you for new knowledge), in Emacs it pushes a mark if I haven't pushed it myself. In Emacs Transient Mark mode is on by default, but mg doesn't have this mode. Also mg doesn't have that N/10 behavior when giving it a numeric arg. In order to be compatible with GNU Emacs, I have to implement Transient Mark mode, make it on by default, while in this mode using M-< and M-> shouldn't push mark if it's active and I have to implement N/10 behavior when giving a numeric arg to M-< and M->, is everything correct?
