[PATCH 1/3] revert: rename --reset option to --quit

[Jonathan Nieder <jrnieder@gmail.com>]

The option to "git cherry-pick" and "git revert" to discard the
sequencer state introduced by v1.7.8-rc0~141^2~6 (revert: Introduce
--reset to remove sequencer state, 2011-08-04) has a confusing name.
Change it now, while we still have the time.

Mechanics:

This commit removes the "git cherry-pick --reset" option.  Hopefully
nobody was using it.  If somebody was, we can add it back again as a
synonym.

The new name for "cherry-pick, please get out of my way, since I've
long forgotten about the sequence of commits I was cherry-picking when
you wrote that old .git/sequencer directory" is --quit.  Mnemonic:
this is analagous to quiting a program the user is no longer using ---
we just want to get out of the multiple-command cherry-pick procedure
and not to reset HEAD or restore any other old state.

Adjust documentation and tests to match.  While at it, let's clarify
the short descriptions of these operations in "-h" output.

Before:

	--reset		forget the current operation
	--continue	continue the current operation

After:

	--quit		end revert or cherry-pick sequence
	--continue	resume revert or cherry-pick sequence
