  $ cd ..

Setup for "cowboy mode" shared mutable history (to illustrate divergent
and bumped changesets).
  $ rm -rf review alice bob
  $ hg clone public alice
  updating to branch default
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg clone public bob
  updating to branch default
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cat >> alice/.hg/hgrc <<EOF
  > [phases]
  > publish = false
  > EOF
  $ cp alice/.hg/hgrc bob/.hg/hgrc

Now we'll have Bob commit a bug fix that could still be improved::

  $ cd bob
  $ echo 'pretty good fix' >> file1
  $ hg commit -u bob -m 'fix bug 24 (v1)'
  $ hg shortlog -r .
  4:2fe6c4bd32d0  draft  fix bug 24 (v1)

Since Alice and Bob are now in cowboy mode, Alice pulls Bob's draft
changeset and amends it herself. ::

  $ cd ../alice
  $ hg pull -u ../bob
  pulling from ../bob
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files
  pull obsolescence markers
  0 obsolescence markers added
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo 'better fix (alice)' >> file1
  $ hg amend -u alice -m 'fix bug 24 (v2 by alice)'

Bob implements a better fix of his own::

  $ cd ../bob
  $ echo 'better fix (bob)' >> file1
  $ hg amend -u bob -m 'fix bug 24 (v2 by bob)'
  $ hg --hidden shortlog -G -r 3::
  @  6:a360947f6faf  draft  fix bug 24 (v2 by bob)

  | x  5:3466c7f5a149  draft  temporary amend commit for 2fe6c4bd32d0

  | x  4:2fe6c4bd32d0  draft  fix bug 24 (v1)
  |/
  o  3:a06ec1bf97bd  public  fix bug 15 (v2)

Bob discovers the divergence.
  $ hg pull ../alice
  pulling from ../alice
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files (+1 heads)
  pull obsolescence markers
  2 obsolescence markers added
  (run 'hg heads' to see heads, 'hg merge' to merge)
  2 new divergent changesets
