Though example is rather strange. This variant will work only if you
put it into an autocmd:

autocmd BufNew * autocmd CursorHold <buffer=abuf> echo 'hold'

. It is not generally incorrect though: the following will work and
contain line from help file literally:

autocmd BufNew * :call DefineAu()
function DefineAu()
:au CursorHold <buffer=abuf> echo 'hold'
endfunction

. But if you read examples without understanding the documentation
first it will be misleading.
