[Orgmode] C-k keystroke kills the subtree

[Dmitry Prokashev]

Hello there.

I'm using org-mode for a several months and recently a sad thing  
happened with me. I suddenly found that a subtree where I look into  
rather rarely, but the information there is quite important,  
disappeared. Obviously I have stroked C-k while the point was located  
on the collapsed tree, and whole my tree disappeared and I did not  
even noticed that. When I found there is no subtree, it was already  
too late to restore it: there was no such change in undo history and  
probably I have removed that subtree in one of my previous emacs  
sessions.

Probably its a good idea to review C-k behaviour in org mode. It may  
remove a single line (subtree header), expand the tree thus attaching  
it to the previous subtree of the same level, for example. And to  
remove the whole collapsed subtree, the user should mark it with a  
region and remove it using C-w thus providing something like a  
confirmation that he really wants to remove the whole subtree. Well  
this is just a set of ideas, but anyway I suppose that C-k should not  
remove the whole (collapsed) tree. My case was the root-level subtree,  
so I've lost about 1/5th of my file.

And yes, thanks for a great tool, this is very usefull for me, and  
good luck!
