Bug#816441: vim: contents of encrypted file can be destroyed without correct password

[Axel]

Package: vim
Version: 2:7.4.488-7
Severity: normal

Dear Maintainer,

if an encrypted file is opened using an incorrect password, the display does not reflect
the encrypted content, but replacing or deleting what is shown will result in the original
content being lost.
