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.

Check pick behavior regarding working copy branch (issue6089)
-------------------------------------------------------------

The branch of the picked changeset should be preserved, and the working copy updated

  $ hg init issue6089
  $ cd issue6089

  $ touch a
  $ hg add a
  $ hg ci -m 'first commit on default'

  $ hg branch foo
  marked working directory as branch foo
  (branches are permanent and global, did you want a bookmark?)
  $ touch b
  $ hg add b
  $ hg ci -m 'first commit on foo'

  $ hg up default
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo test > a
  $ hg ci -m 'second commit on default'
  $ hg log -G --template '{node|short}: {branch}\n' --rev 'all()+wdir()'
  o  ffffffffffff: default
  |
  @  5f07cbf7d111: default
  |
  | o  96bb2057779e: foo
  |/
  o  d03a6bcc83cd: default
  

  $ hg pick 1
  picking 1:96bb2057779e "first commit on foo"
  $ hg log --template '{branch}\n' -r tip
  foo
  $ hg branch
  foo
  $ hg log -G --template '{node|short}: {branch}\n' --rev 'all()+wdir()'
  o  ffffffffffff: foo
  |
  @  5344a77549bd: foo
  |
  o  5f07cbf7d111: default
  |
  o  d03a6bcc83cd: default
  
  $ cd ..

Check that pick doesn't drop files after conflicts occur (issue6037)
--------------------------------------------------------------------

  $ hg init issue6037
  $ cd issue6037

  $ echo apple > a
  $ hg ci -qAm 'apple'

  $ echo apricot > a
  $ echo banana > b
  $ hg ci -qAm 'apricot and banana'

  $ echo avocado > a
  $ hg ci -m 'avocado'

  $ hg glf
  @  2: avocado (a)
  |
  o  1: apricot and banana (a b)
  |
  o  0: apple (a)
  
Now let's change order of 1 and 2 using pick command

  $ hg up -r 0
  1 files updated, 0 files merged, 1 files removed, 0 files unresolved

We avoid merge conflict here just to make the test shorter

  $ hg pick -r 2 --tool :other
  picking 2:f08a1e4a33c4 "avocado"

Now we pick revision 1 that touches two files (a and b), merge conflict is expected

  $ hg pick -r 1
  picking 1:892e123ebf62 "apricot and banana"
  merging a
  warning: conflicts while merging a! (edit, then use 'hg resolve --mark')
  unresolved merge conflicts (see hg help resolve)
  [1]
  $ hg resolve -t :other a
  (no more unresolved files)
  continue: hg pick --continue
  $ hg pick --continue

Demonstrate that b was not forgotten and is definitely included in 4

  $ hg status b -A
  C b
  $ hg glf
  @  4: apricot and banana (a b)
  |
  o  3: avocado (a)
  |
  o  0: apple (a)
  
  $ cd ..
