" First make sure nothing is written to ~/.viminfo while editing
" an encrypted file.
autocmd BufReadPre,FileReadPre      *.gpg set viminfo=
" We don't want a swap file, as it writes unencrypted data to disk
autocmd BufReadPre,FileReadPre      *.gpg set noswapfile
" Switch to binary mode to read the encrypted file
autocmd BufReadPre,FileReadPre      *.gpg set bin
autocmd BufReadPre,FileReadPre      *.gpg let ch_save = &ch|set ch=2
autocmd BufReadPre,FileReadPre      *.gpg let shsave=&sh
