topic: correctly update from public commits with a (now hidden) topic

Test script based on sharing.rst: ensure that all scenarios in that
document work as advertised.

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
  pushing to $TESTTMP/public (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files

and pull that into the development repository::

  $ cd ../dev-repo
  $ hg pull -u
  pulling from $TESTTMP/test-repo (glob)
  requesting all changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files
  new changesets 0dc9c9f6ab91
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

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 -R ../dev-repo shortlog -G

  $ hg -R ../test-repo shortlog -G

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'
  $ echo 'Fix fix fix.' > file1
  $ hg amend -m'fix bug 37'
