Is there any difference between the following two commands:

autocmd FileType html,htmldjango inoremap <buffer> <leader>1 &nbsp;

And converted to an autocmd:

augroup filetype_html
    autocmd!
    autocmd FileType html,htmldjango inoremap <buffer> <leader>1 &nbsp;
augroup END

Is one preferable over the other, or are they two different ways of saying the same thing? If so, why should one be used over the other?

Always use augroup followed by autocmd!. Period.

The major problem is that executing

autocmd BufRead * echomsg 'foobar'

twice will result in printing foobar twice per each BufRead.
