[PATCH v4] rebase: clarify "restore the original branch"

[Martin von Zweigbergk <martin.von.zweigbergk@gmail.com>]

The description for 'git rebase --abort' currently says:

    Restore the original branch and abort the rebase operation.

The "restore" can be misinterpreted to imply that the original branch
was somehow in a broken state during the rebase operation. It is also
not completely clear what "the original branch" is --- is it the
branch that was checked out before the rebase operation was called or
is the the branch that is being rebased (it is the latter)? Although
both issues are made clear in the DESCRIPTION section, let us also
make the entry in the OPTIONS secion more clear.

Also remove the term "rebasing process" from the usage text, since the
user already knows that the text is about "git rebase".

While reading some sample output in an unrelated mail from Jeff, I
noticed that we actually use "restore" in a few more places (I had
originally seached for "abort" to find places to update). This patch
fixes those places.

I used the term "check out" instead of "reset HEAD to", because I
think the concept feels more familiar to many people, even though
"reset HEAD to" is technically more correct.

The phrase "restore the original branch" is also used in git-am, where
I think it makes even less sense. I rarely use git-am, but I think it
always applies the patches to the current branch, so there "restore
the original branch" really means "resets the (current) branch to the
original position (where it was when git-am was started)", doesn't it?
