I found that the problem was caused by a <silent> keyword in a cmap:
fun! X()
return getcmdline()
endfun
" This map will not redraw the command line:
cnoremap <silent> <CR> <C-\>eX()<CR><CR>
" This map will redraw the command line:
cnoremap <CR> <C-\>eX()<CR><CR>
And actually all cmaps behave like that. Maybe we should add
:cmap-<silent> just after ":help :map-<silent>" in the help file. If so
I can write a patch for the documentation.
Best regards,
