No problem with me.

I didn't know those functions, which make life definitely easier.
(Mapping `:' was also smarter than my way; the best solution would be a
CmdEnter autocommand, but there is none.)

That's because you forgot to retrieve the command typed so far. So
here's a reworking of your solution. It also skips empty arguments:
let s:indx=histnr("cmd")
function! GetArg()
let l:head = matchstr(getcmdline(), '^\S*')
let l:cmdl = ""
while s:indx >= 0 && l:cmdl == ""
let l:cmdl = matchstr(histget("cmd", s:indx), '\s\zs.*')
let s:indx -= 1
endwhile
return l:head . " " . l:cmdl
endfunction
function! InitIndex()
let s:indx=histnr("cmd")
return ""
endfunction
cnoremap <M-.> <C-E><C-\>eGetArg()<CR>
nnoremap : :<C-\>eInitIndex()<CR>
I hope this time it'll work ok.
Best,
Paul
