v1: Documentation: updates and a correction around 'ORIG_HEAD'

This series' initial motivation was to clear up a confusion that arose in
[1] where it was noticed that 'ORIG_HEAD' is not guaranteed to point to the
original branch tip at the end of the rebase if 'git reset' is used during
the rebase.

Patch 5/5 adds a note to 'git rebase's documentation to make that explicit.
When taking a look at the existing documentation mentioning 'ORIG_HEAD', I
also found an error in an example (patch 1/5), other small inconsistencies
(patch 2-3/5), and a potential improvement (patch 4/5).

Cheers,

Philippe.

          Indeed, using other commands that write 'ORIG_HEAD' during the rebase,
          like splitting a commit using 'git reset HEAD^', will lead to 'ORIG_HEAD'
     -    being overwritten.
     +    being overwritten. This causes confusion for some users [1].
      
          Add a note about that in the 'Description' section, and mention the more
          robust alternative of using the branch's reflog.
