:h 'diffopt'. You can use "-c 'set diffopt+=iwhite'" to specify this option at the command-line, but it may be too late. Specifying it in the vimrc will not, but it is not convenient, thus you may want to use something like

    if !empty('$VIMDIFFOPT')
        let &diffopt=$VIMDIFFOPT
    endif

that enables taking this option from environment variable VIMDIFFOPT.
