I find this notation fairly unintuitive.  I'm more inclined to let users 
specify their own names for important parts of the rebase.

I guess that's what Junio's 'mark' command is for, but not having seen a 
proper explanation of 'mark', I suggest instead a more inline method: an 
'as' keyword.  Any command in a todo script can be followed (on the same 
line, before the SHA1 value) with 'as <name>' allowing <name> to appear 
later in the script to refer to the result of the earlier command.

So the script in the example becomes

	pick as start A
	pick C
	pick as bottom D
	goto start
	pick B
	merge bottom was E

I find that much easier to understand.  Especially when real SHA1 values 
are floating around everywhere, I think this notation will help users 
get things right.

This approach also allows a commit name "A" to consistently refer to the 
original commit, which I think also makes things easier for users.
