default / fallback: suppress prompt?

[Matthias Strelow]

Hi grub team / users.
Can anyone help me with this?
If I specify a default and a fallback entry,
when default fails, there's a prompt "Press any key to continue".
is there any way to suppress this, and behave like described in the man
page
"instead of waiting for the user to do anything, immediately start over
using the num entry"
thanks in advance
Matthias
