Test file dedicated to testing the divergent troubles from obsolete changeset.

This is the most complexe troubles from far so we isolate it in a dedicated

file.

Enable obsolete

  $ cat > obs.py << EOF

  > import mercurial.obsolete

  > mercurial.obsolete._enabled = True

  > EOF

  $ cat >> $HGRCPATH << EOF

  > [ui]

  > logtemplate = {rev}:{node|short} {desc}\n

  > [extensions]

  > obs=${TESTTMP}/obs.py

  > [alias]

  > debugobsolete = debugobsolete -d '0 0'

  > [phases]

  > publish=False

  > EOF

  $ mkcommit() {

  >    echo "$1" > "$1"

  >    hg add "$1"

  >    hg ci -m "$1"

  > }

  $ getid() {

  >    hg id --debug -ir "desc('$1')"
