    I use this daily. Though to be safe; I do a diff of current buffer and file saved on disk before reverting.
    0 set diffopt+=iwhite
    1 function! DiffOrig()
    2 if &diff
    3 wincmd p | bdel | diffoff
    4 else
    5 vert new | set bt=nofile | r # | 0d_ | diffthis | wincmd p | diffthis
    6 endif
    7 endfunction
    8 map do :call DiffOrig()

    easiest way is, type escape and then “u” to undo the changes one by one.
