To start things off, let's make one public, immutable changeset::
$ cd test-repo
$ echo 'my new project' > file1
$ hg add file1
$ hg commit -m'create new project'
$ hg push -q
and pull that into the development repository::
$ cd ../dev-repo
$ hg pull -q -u
Let's commit a preliminary change and push it to ``test-repo`` for
testing. ::
$ echo 'fix fix fix' > file1
$ hg commit -m'prelim change'
$ hg push -q ../test-repo
Figure SG01 (roughly)
$ hg shortlog -G

o 0:0dc9c9f6ab91 public create new project
Now let's switch to test-repo to test our change and amend::
$ cd ../test-repo
$ hg update -q
$ echo 'Fix fix fix.' > file1
$ hg amend -m'fix bug 37'

Sharing by Alice and Bob to demonstrate bumped and divergent changesets.
First, setup repos for them.
$ cd ..
$ hg clone -q public alice
$ hg clone -q public bob
$ cat >> alice/.hg/hgrc <<EOF
> [phases]
> publish = false
> EOF
$ cp alice/.hg/hgrc bob/.hg/hgrc
Alice commits a bug fix.
$ cd alice
$ echo 'fix' > file2
$ hg commit -q -A -u alice -m 'fix bug 15'
Bob pulls and amends Alice's fix.
$ cd ../bob
$ hg pull -q -u ../alice
$ echo 'Fix.' > file2
$ hg amend -q -A -u bob -m 'fix bug 15 (amended)'

But in the meantime, Alice decides the fix is just fine and publishes it.
$ cd ../alice
$ hg push -q
Which means that Bob now has an formerly obsolete changeset that is
also public (2:6e83). As soon as he pulls its phase change, he's got
trouble: the successors of that formerly obsolete changeset are
bumped.

Throw away Bob's messy repo and start over.
$ cd ..
$ rm -rf bob
$ cp -rp alice bob
Bob commits a pretty good fix that both he and Alice will amend,
leading to divergence.
$ cd bob
$ echo 'pretty good fix' >> file1
$ hg commit -u bob -m 'fix bug 24 (v1)'
Alice pulls Bob's fix and improves it.
$ cd ../alice
$ hg pull -q -u ../bob
$ echo 'better (alice)' >> file1
$ hg amend -u alice -m 'fix bug 24 (v2 by alice)'
Likewise, Bob amends his own fix. Now we have an obsolete changeset
with two successors, although the successors are in different repos.
$ cd ../bob
$ echo 'better (bob)' >> file1
$ hg amend -u bob -m 'fix bug 24 (v2 by bob)'
Bob pulls from Alice's repo and discovers the trouble: divergent changesets!
$ hg pull -q -u ../alice
not updating: not a linear update
(merge or update --check to force update)
2 new divergent changesets
$ hg shortlog -r 'divergent()'
