cmdline.c: ESC at any time exits: only mentioned once

Gentlemen, there is a serious usability problem with cmdline.c.

At the very start the user sees the message made by

  grub_printf ("\
 [ Minimal BASH-like line editing is supported. For the first word, TAB\n\
   lists possible command completions. Anywhere else TAB lists possible\n\
   device/file completions.%s ]\n\n",
               nested ? " ESC at any time exits." : "");

The problem is, just let him type "help" just once...

The note about "ESC at any time exits" is now gone from the screen.

He now faces a list of the help commands, with NO "exit" or "quit"

No. Not even the tiniest hint left about how to get back out.

> If he is smart he would have remembered "ESC at any time exits".

But he is just average, not smart.

He ends up choosing "reboot", the only choice that seems like it will
get him BACK.

Therefore, please add
"ESC at any time exits" to the bottom of the help list.

No, I don't know how to make this patch.

You will have to do it for me.

Also note the help list must still fit on one screen after the patch.

Thank you.
