:enew discards my changes

[12425]

I lost all my changes in an unsaved buffer and the swap file was even gone.

I have a key map for <F1>: :enew
When I was in CtrlP, I accidently pressed it and the buffer was gone!

You can reproduce it as below:

1. Open Vim and input anything (after that, the buffer is modified).
2. :nnoremap <F1> :enew<CR>
3. :CtrlP
4. Press <F1>
5. Where is the modified buffer? Where is the swap file?
