The order matters - putting bookmarks or moving working copy on non-obsoleted
commits do not pin them. Test this using "debugobsolete" which will not call
"createmarkers".

Obsolete working copy, and move working copy away should make things disappear

  $ rm -rf .hg && hg init && hg debugdrawdag <<'EOS'
  > C E
  > | |
  > B D
  > |/
  > A
  > EOS

  $ hg up -q E
  $ hg debugobsolete `HGPLAIN=1 hg log -r E -T '{node}'`
  obsoleted 1 changesets
  $ hg tag --local --remove E
  $ hg log -G -T '{rev} {desc}\n'
  @  4 E

  o  0 A
  
  $ hg debugobsolete `HGPLAIN=1 hg log -r D -T '{node}'`

  $ hg tag --local --remove D
  $ hg log -G -T '{rev} {desc}\n'

Having a bookmark on a commit, obsolete the commit, remove the bookmark

  $ rm -rf .hg && hg init && hg debugdrawdag <<'EOS'
  > C E

  > B D

  > A
  > EOS

  $ hg bookmark -i book-e -r E
  $ hg debugobsolete `HGPLAIN=1 hg log -r D -T '{node}'`
  obsoleted 1 changesets
  $ hg debugobsolete `HGPLAIN=1 hg log -r E -T '{node}'`
  obsoleted 1 changesets
  $ rm .hg/localtags
  $ hg log -G -T '{rev} {desc} {bookmarks}\n'
  x  4 E book-e

  $ hg bookmark -d book-e
  $ hg log -G -T '{rev} {desc} {bookmarks}\n'
