: 
: The GRUB shell is not equal to bash. It is a small shell which
: implements the commands listed by the "help" command. The only form of
: TAB completion it offers is completion of GRUB commands. E.g. when you
: type "partn" and hit TAB, it completes to "partnew". Or when you enter
: "con" and hit TAB, it completes to "configfile".

When I hit TAB, the cursor just moves over (on the F7 x86_64 machine).
On all my other machines (1 FC5 32bit machine, 2 FC6 32bit machines,
1 FC6 64bit machine) grub TAB completion, and the other bash-like
editing commands, work correctly.  I'm beginning to think this is a
bug in the F7 64-bit package.

I rebooted, got into that environment, and TAB completion works!  I am
now even more at a loss (and I was already entirely at a loss :-).
