Test autorepack

  $ ls .hg/dirstate.tree.*
  .hg/dirstate.tree.* (glob)
  $ echo data > file

After the first repack, the old trees are kept around by the transaction undo backups.
  $ hg add file --config treestate.minrepackthreshold=1 --config treestate.repackfactor=0 --debug | grep -v 'in use by'
  adding file
  auto-repacking treedirstate
  $ ls .hg/dirstate.tree.*
  .hg/dirstate.tree.* (glob)
  .hg/dirstate.tree.* (glob)

After the second repack, the old trees are still kept around.
  $ hg forget file --config treestate.minrepackthreshold=1 --config treestate.repackfactor=0 --debug | grep -v 'in use by'
  removing file
  auto-repacking treedirstate
  $ ls .hg/dirstate.tree.*
  .hg/dirstate.tree.* (glob)
  .hg/dirstate.tree.* (glob)
  .hg/dirstate.tree.* (glob)

On the third repack, the original tree is removed.
  $ hg add file --config treestate.minrepackthreshold=1 --config treestate.repackfactor=0 --debug | grep -v 'in use by'
  adding file
  auto-repacking treedirstate

  $ ls .hg/dirstate.tree.*
  .hg/dirstate.tree.* (glob)

On the fourth repack, the second tree is removed.
  $ hg forget file --config treestate.minrepackthreshold=1 --config treestate.repackfactor=0 --debug | grep -v 'in use by'
