Searching for "echo" in todo.txt, I did not find any mention of
this. Maybe this item?
9 Check handling of overwriting of messages and delays:
Very wrong: errors while redrawing cause endless loop.
When switching to another file and screen scrolls because of the long
message and return must be typed, don't scroll the screen back before
redrawing.
It seems to me that the message is wiped out when the screen
scrolls. If the cursor move on the same screen, or if the screen
redraws, then I see the "bla bla". Aha: this seems to help:
:nnoremap * :execute "norm! *" <Bar> redraw <Bar> echomsg "bla bla"<CR>
