If i edit an snippets, it is automatically saved.

Means:
* open an snippet to modify
* modify
* close the tab
Snippet is modified! No question, no [OK]

What sounds fine first can messing-up our snippets
if we play around and close the edit-tab,
while thinking we will be asked to save or not.
Or think this closing without Ctrl+S is like canceling.
But instead our mess is saved automatically.

I think, once closed there is no way to undo an modification.

Is this the indented behavior?
Shouldn't we be asked to save if doc is dirty?
Like an normal document too.
