The meaning of x~0 and x~ as rev-spec.

Hello,

Testing suggests that <name>~0 and <name>~ are the same and are just synonyms for <name> as rev-specs. Is that correct? Is that by design, or by accident?

Shouldn't <name>~0 have [the same] special meaning as <name>^0?

Shouldn't <name>~ be a short-cut for <name>~1, similar to <name>^?

Anyway, I think that at least <name>~0 (useful for scripting) should be explicitly documented, provided that <name>^0 has special (and documented) meaning.

[ The question arose when I wanted to write something like this to automate reverting of a few last revisions:

  for i in 0 1 2 3; do
      git revert -n HEAD~$i
  done
  git commit -a
