vimdiff ignore empty lines

Add this to the end of your .vimrc file to make vimdiff ignore empty lines:


set diffopt+=iwhite
set diffexpr=MyDiff()
function MyDiff()
    let opt = ""
    if &diffopt =~ "icase"
        let opt = opt . "-i "
    endif
    if &diffopt =~ "iwhite"
        let opt = opt . "-w -B " " vim uses -b by default
    endif
    silent execute "!diff -a --binary " . opt .
                \ v:fname_in . " " . v:fname_new .  " > " . v:fname_out
endfunction
