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

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

[Sergei Organov]

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

sed -n -e '/name~3/,/x = 0;/p' sha1_name.c

OK, I'll send a patch for documentation.
