This might be an overkill, and perhaps dangerous, but it seems to
work:

let s:CmdHistory = []
let s:CmdCount = -1
function! ResetCmd()
let s:CmdCount = len(s:CmdHistory) - 1
return ""
endfunction

function! StoreCmd()
let cmd = matchstr(getcmdline(), '\s.\+')
call add(s:CmdHistory, cmd)
let s:CmdCount = len(s:CmdHistory) - 1
return getcmdline()
endfunction

function! GetCmd()
if s:CmdCount >= 0
let cmd = matchstr(getcmdline(), '^\S*') . s:CmdHistory[s:CmdCount]
let s:CmdCount = s:CmdCount - 1
return cmd
else
return getcmdline()
endif
endfunction

cnoremap <buffer> <CR> <C-\>eStoreCmd()<CR><CR>
cnoremap <buffer> <Esc> <C-\>eResetCmd()<CR><Esc>
cnoremap <buffer> <A-.> <C-\>eGetCmd()<CR>

Also, I'm not very fluent in Vimscript (I tend to script in Lua with Vim
functions simply as wrappers), so this might be improvable.

Best,
Paul
