Copying and pasting examples literally is dangerous. You should know
what you are doing.

"..." is a revision range that computes the mergebase between HEAD
and HEAD, which is (surprise!) HEAD, and then includes the two end
points, but excludes everything below the mergebase. So, the revision
specification that your command ends up with is

      HEAD HEAD ^HEAD ^67d9d9 f70bf4

Which is empty if f70bf4 is an ancestor of HEAD.

[LU Chuck] Sorry, I can't understand this part, did you have an documentation

about the explanation for ...?

[LU Chuck] Thanks for your documentation about the explanation. Previously I read another documentation https://git-scm.com/book/en/v2/Git-Tools-Revision-Selection#Commit-Ranges.  
          It's weird the three dots has two different explanation, maybe there should a place to collect these two explanation for three dots.

          "computes the mergebase between HEAD and HEAD" I have no idea

about this. And you also talked about mergebase, but in my situation, there is only
one branch with 5 commits. I did not have a mergebase.

          You can check the detail description below.

When there is no specific revisions around the three dots then HEAD is assumed
(to save typing)

[LU Chuck] I got you here, that's why you ask me remove the three dots before, right?
