Currently testing some big changes I have done on undo.c and yank.c cause it does not perform well on +65k rows.
The idea is to malloc as much we need and avoid small mallocs.
Will create a new dev branch on github soon.

Thanks to all that helped and created PR.
Thanks to all who support and use this program.
