" example of how you would use it:
"
" :command -nargs=* -complete=customlist,xolox#misc#complete#keywords MyCmd call s:MyCmd(<f-args>)
let words = {}
for line in getline(1, '$')
for word in split(line, '\W\+')
let words[word] = 1
endfor
endfor
return sort(keys(filter(words, 'v:key =~# a:arglead')))
endfunction
