GRUB command line

I have a few minor suggestions for the command line interface and
the documentation thereof. Situation was this:

I boot, grub is started. When the menu is shown, I press c for the
command line. After typing a few commands, I realize why one of my
menu entries doesn't work. Now I want to get back to the manu, select a
different entry to boot into the operating system so I can correct my
error. But I couldn't easily find out how to do that; best I could
find was the reboot command.

It turneds out I could have used ESC to get back, but I didn't find
that at the time. It's mentioned in the message displayed wen entering
command line mode (but that information had scrolled away by the time
I needed it), but it's not mentioned in the message I get when typing
"help". It's also documented in the manual
(http://www.gnu.org/software/grub/manual/grub.html#Interface), but in
section 12.2 "The simple menu interface", not in section 12.1 "The
flexible command-line interface" which lists other key bindings. I'd

1. Mention ESC in section 12.1 in the manual, with the rest of the key

2. Mention it in the help message displayed if I type "help" to the
   command line interface.

3. Define the "quit" command (currently available only or grub-shell)
   to do the same thing; exit the command line and return to the menu.

Also, when composing this message, I should tell you the version of
grub I'm using. According to grub-install --version after I've booted,
I'm using GNU Grub 0.97, but this is not necessarily the same version
as the one I have on the boot sector. And there's no version command
for the command line. So I'd also suggest

4. Add a "version" command to the command line interface. It should
   probably display version information for all the different stages,
   in case they for some reason are different.
