A ajuda afirma isso:
The plugin has a default place where to look for spell files, on the Vim ftp
server. If you want to use another location or another protocol, set the
g:spellfile_URL variable to the directory that holds the spell files. The
netrw plugin is used for getting the file, look there for the specific
syntax of the URL. Example:
let g:spellfile_URL = 'http://ftp.vim.org/vim/runtime/spell'
You may need to escape special characters.
The plugin will only ask about downloading a language once. If you want to
try again anyway restart Vim, or set g:spellfile_URL to another value (e.g.,
prepend a space).
Observe que a escolha padrão em cada interação é negativa.
Por exemplo, o seguinte acontece se você digitar :set spelllang=fr
e o idioma francês ainda não estiver instalado).
