docs: add two more amend commits to simulate temporary amend commits

sharing.rst made reference to temporary amend commits and used them to
demonstrate that hidden commits are not exchanged. Nowadays, evolve doesn't
create such commits, but it still makes sense to show how they are handled
during the exchange process. So let's add two more amend commits, one for each
repo. This way the guide doesn't have to be updated too much, but doesn't lose
this important detail of working with evolve.

Unfortunately, this means that tons of hashes change, but it's better than to
have figure 4 demonstrate absolutely nothing.

Temporary amend commits were removed from test-sharing.t in 06844693bb21,
but sharing.rst continued using them for demonstration purposes. It might've
been better to replace at least some of the temporary amend commits by extra
amends back then, but oh well.

=======================================================
Tests the resolution of content divergence: interrupted
=======================================================

This file intend to cover case where evolve has to be interrupted.

This test aims at gather test case for --abort, --continue and --stop


Tests for the --abort flag for `hg evolve` command while content-divergence resolution
======================================================================================

The `--abort` flag aborts the interrupted evolve by undoing all the work which
was done during resolution i.e. stripping new changesets created, moving
bookmarks back, moving working directory back.

This test contains cases when `hg evolve` is doing content-divergence resolution.

Setup
=====

  $ cat >> $HGRCPATH <<EOF
  > [phases]
  > publish = False
  > [alias]
  > glog = log -GT "{rev}:{node|short} {desc}\n ({bookmarks}) {phase}"
  > [extensions]
  > EOF
  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH

  $ hg init abortrepo
  $ cd abortrepo
  $ echo ".*\.orig" > .hgignore
  $ hg add .hgignore
  $ hg ci -m "added hgignore"
  $ for ch in a b c d; do echo foo > $ch; hg add $ch; hg ci -qm "added "$ch; done;

Tests for the --stop flag for `hg evolve` command while resolving content-divergence
==================================================================================

The `--stop` flag stops the interrupted evolution and delete the state file so
user can do other things and comeback and do evolution later on

This is testing cases when `hg evolve` command is doing content-divergence resolution.

Setup
=====

  $ hg init stoprepo
  $ cd stoprepo
  $ echo ".*\.orig" > .hgignore
  $ hg add .hgignore
  $ hg ci -m "added hgignore"
  $ for ch in a b c d; do echo foo > $ch; hg add $ch; hg ci -qm "added "$ch; done;
