[PATCH v2] rebase -i: support single-letter abbreviations for the actions

[Johannes Schindelin <Johannes.Schindelin@gmx.de>]

When you do many rebases, you can get annoyed by having to type out
the actions "edit" or "squash" in total.

This commit helps that, by allowing you to enter "e" instead of "edit",
"p" instead of "pick", or "s" instead of "squash".

	Okay, you convinced me.

	I thought that this would be possible with "git rebase -p -i"?

	Ah no, that does not work; "-p" is not yet graceful enough to 
	accept reorders.  (But then, I do not see why the command should 
	be "merge" instead of the "pick" we already have...)
