+= does not do appending, it does addition. "diffopt" is not a vim variable, it is option and & is a sigil denoting option. There is no appending taking place here: you need

    let &diffopt.=(empty(&diffopt)?'':',').$VIMDIFFOPT

(.= is appending). You should never confuse :let and :set.

Nikolay et al:

     Thanks, "sigil" is a new word for me.

     I do not know why everyone is so worried about -c being executed too late.  I often

:set diffopt+=iwhite

after starting vimdiff, so why would doing it at the command line be too late?  Just to be sure, I tried

$ vim -d -c "set diffopt+=iwhite" *.patch

and it worked as expected.  As a further test, I added "set diffopt=" to my vimrc, and it still worked fine.

     Since most people do not know a given option exists, I recommend

:options

and then browse what is available.
