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: metadata
+====================================================

This file intend to cover cases focused around meta data merging.

Setup
-----

  $ cat >> $HGRCPATH <<EOF
  > [alias]
  > glog = log -GT "{rev}:{node|short} {desc|firstline}\n {phase} {instabilities}\n\n"
  > [phases]
  > publish = False

  > rebase =
  > EOF
  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH

Check we preserve the author properly
-------------------------------------

Testing issue6113 to make sure that content-divergence resolution don't
replace initial author with the user running the resolution command:

  $ hg init userfoo
  $ cd userfoo
  $ unset HGUSER
  $ echo "[ui]" >> ./.hg/hgrc
  $ echo "username = foo <[e-mail]>" >> ./.hg/hgrc
  $ for ch in a b c; do
  > echo $ch > $ch;
  > hg add $ch;
  > hg ci -m "added "$ch;
  > done;

  $ cd ..
  $ hg init userbar
  $ cd userbar
  $ unset HGUSER
  $ echo "[ui]" >> ./.hg/hgrc
  $ echo "username = bar <[e-mail]>" >> ./.hg/hgrc
  $ hg pull ./../userfoo -q

  $ cd ../userfoo
  $ hg up -r "desc('added b')"
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo c > c
  $ echo e > e
  $ hg add c e
  $ hg ci -m "added c e"
  created new head

  $ hg up -r "desc('added b')"
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ echo cc > c
  $ hg add c
  $ hg ci -m "added c"
  created new head

  $ hg prune -r "min(desc('added c'))" -s "desc('added c e')"
  1 changesets pruned
  $ hg prune -r "min(desc('added c'))" -s "max(desc('added c'))" --hidden
  1 changesets pruned
  2 new content-divergent changesets

  $ hg glog
  @  4:6c06cda6dc99 added c
  |   draft content-divergent
  |
  | *  3:0c9267e23c9d added c e
  |/    draft content-divergent
  |
  o  1:1740ad2a1eda added b
  |   draft
  |
  o  0:f863f39764c4 added a
      draft
  

  $ cd ../userbar
  $ hg pull ./../userfoo -q
  2 new content-divergent changesets

  $ hg evolve --content-divergent --any
  merge:[3] added c e
  with: [4] added c
  base: [2] added c
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

Make sure resultant cset don't replace the initial user with user running the command:
  $ hg log -r tip
  changeset:   5:443bd2972210
  tag:         tip
  parent:      1:1740ad2a1eda
  user:        foo <[e-mail]>
  date:        Thu Jan 01 00:00:00 1970 +0000
  summary:     added c e
  
  $ cd ..

Testing the three way merge logic for user of content divergent changesets
--------------------------------------------------------------------------

  $ hg init mergeusers
  $ cd mergeusers
  $ for ch in a b c; do
  > touch $ch
  > hg add $ch
  > hg ci -m "added "$ch
  > done;

  $ hg amend -m "updated c"
  $ hg up -r 'desc("added c")' --hidden -q
  updated to hidden changeset 2b3c31fe982d
  (hidden revision '2b3c31fe982d' was rewritten as: 464e35020fd0)
  working directory parent is obsolete! (2b3c31fe982d)
  $ echo coco > c

1) when one user is different wrt base
--------------------------------------

Insert a diverging author name:
  $ hg amend -u 'foouser'
  2 new content-divergent changesets

Run automatic evolution:
  $ hg evolve --content-divergent
  merge:[3] updated c
  with: [4] added c
  base: [2] added c
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  working directory is now at 932d6ceb7672

  $ hg log -r tip | grep "^user"
  user:        foouser

  $ hg strip . -q --config extensions.strip=
  2 new content-divergent changesets

2) when both the user are different wrt base
--------------------------------------------

  $ hg up -r 'max(desc("updated c"))'
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg amend -u 'baruser'

Run automatic evolution:
  $ hg evolve --content-divergent
  merge:[4] added c
  with: [5] updated c
  base: [2] added c
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  working directory is now at 202a770d8c1f

  $ hg log -r tip | grep "^user"
  user:        baruser, foouser

  $ cd ..
