Setup the server

  $ hginit master
  $ cd master
  $ cat >> .hg/hgrc <<EOF
  > [treemanifest]
  > server=True
  > [remotefilelog]
  > server=True
  > shallowtrees=True
  > EOF

Make local commits on the server
  $ mkdir subdir
  $ echo x > subdir/x
  $ hg commit -qAm 'add subdir/x'
  $ hg book master

The following will turn on sendtrees mode for a hybrid client and verify it
sends them during a push and during bundle operations.

Create flat manifest clients
  $ cd ..
  $ hgcloneshallow ssh://user@dummy/master client1 -q
  fetching tree '' 85b359fdb09e9b8d7ac4a74551612b277345e8fd
  2 trees fetched over * (glob)
  1 files fetched over 1 fetches - (1 misses, 0.00% hit ratio) over * (glob) (?)
  $ hgcloneshallow ssh://user@dummy/master client2 -q

Transition to hybrid flat+tree client
  $ cat >> client1/.hg/hgrc <<EOF
  > [extensions]
  > amend=
  > [treemanifest]
  > demanddownload=True
  > EOF
  $ cat >> client2/.hg/hgrc <<EOF
  > [extensions]
  > amend=
  > [treemanifest]
  > demanddownload=True
  > EOF

  $ cd client1
  $ echo f >> subdir/x
  $ hg commit -qm "hybrid commit"
