[RFD] How to better document the "two and three dots" format

["Paolo Ciarrocchi" <paolo.ciarrocchi@gmail.com>]

Hi all,
I'm looking in the existing documentation about some example and
clarification about
the two and three dots formats applied to git diff.

The git-diff.txt file includes the following:

---8<---
Comparing branches::
+
------------
$ git diff topic master    <1>
$ git diff topic..master   <2>
$ git diff topic...master  <3>
------------
+
<1> Changes between the tips of the topic and the master branches.
<2> Same as above.
<3> Changes that occurred on the master branch since when the topic
branch was started off it.
---8<---

I think <3> should be changed in something like:
<3> Changes between the tips of the topic and the master branch that
occurred since when the topic
branch was started off it.

What do you think?

I would like to add some graphical representation of <2> and <3> but
I'm a bit loss
with <3> (and I guess lot of newbies are not really understanding that point).
Can anybody come up with some ASCII art?

Thanks.

Ciao,
