I would like to set different vimdiff options by filetype . . . in

I added the following to the rc file, but I still get "iwhite" set
in diffopt for python files:
set diffopt+=iwhite
if &filetype == 'python'
set diffopt-=iwhite
endif
I'm probably missing something obvious :-))
It's obvious only after some experience with Vim. It's in the
documentation, but not in one place.
The problem is that Vim determines filetypes after it reads
~/.vimrc; 'filetype' is not set when that if statement is executed.
One way to fix that is to use these commands instead:
set diffopt+=iwhite
au FileType python set diffopt-=iwhite
Note that 'diffopt' is a global option; it can't be set differently
for different buffers. Therefore, the autocommand above will remove
"iwhite" from 'diffopt' whenever you edit a Python file and not
restore "iwhite" if you later diff two buffers of a different
filetype. Whether that's a problem for you and how you might fix
that depends on how you use Vim.

Sorry for going off topic a little, but is the order that .vimrc,
.vim/plugin/* etc. are read listed somewhere?
