input() doesn't work when called from normal command

[mattn]

Hi.

---
function! s:confirm_and_input()
let a = confirm("Your Sex?", "Male\nFemale")
echo input("Your Name?", )
endfunction

nnoremap <buffer> <c-d> :call <SID>confirm_and_input()<cr>
exe "normal \<c-d>"
---

When :so this script, confirm() works well but input() doesn't.
input() return empty string always. This caused that ex_normal_busy flag is
not zero. I think this should be worked even-though called from normal command. Below is a patch.
Please check.

Thanks. I wonder if there are side effects. There was a reason it was
done the way it is, but I don't immediately recall what it was.

I guess that it is the way to do graceful for displaying without "-- hit return --" when it called from normal command.
