Or even better, detect by the content:

    if search('\m\C^--- .*\n+++ .*\n@@','n')
        setlocal filetype=diff
    endif

It works with things like "git show" and "git log -p" too. Here's updated version for those who are interested:

    command! -complete=file -nargs=* Git call s:RunShellCommand('git '.<q-args>)

    " To run any shell command:
    "command! -complete=file -nargs=+ Shell call s:RunShellCommand(<q-args>)

    " Additional $VCS commands:
    "command! -complete=file -nargs=* Hg call s:RunShellCommand('hg '.<q-args>)
    "command! -complete=file -nargs=* Svn call s:RunShellCommand('svn '.<q-args>)
    "command! -complete=file -nargs=* Bzr call s:RunShellCommand('bzr '.<q-args>)

    " In case a shell command wants to open $EDITOR we use something
    " that works from inside Vim.
    let $EDITOR = '/usr/bin/gvim --nofork'

    function! s:RunShellCommand(cmdline)
        botright new
        setlocal buftype=nofile bufhidden=wipe nobuflisted noswapfile nowrap
        call setline(1,a:cmdline)
        call setline(2,substitute(a:cmdline,'.','=','g'))
        execute 'silent $read !'.escape(a:cmdline,'()%#')
        setlocal nomodifiable
        if search('\m\C^--- .*\n+++ .*\n@@','n')
            setlocal filetype=diff
        endif
        1
    endfunction
