test sparse with --verbose and -T json

  $ hg init myrepo
  $ cd myrepo
  $ cat > .hg/hgrc <<EOF
  > [extensions]
  > sparse=$TESTDIR/../hgext/fbsparse.py
  > strip=
  > EOF

  $ echo a > show
  $ echo x > hide
  $ hg ci -Aqm 'initial'

  $ echo b > show
  $ echo y > hide
  $ echo aa > show2
  $ echo xx > hide2
  $ hg ci -Aqm 'two'

Verify basic --include and reset

  $ hg up -q 0
  $ hg sparse --include 'hide' -Tjson

Verifying that problematic files still allow us to see the deltas when forcing:

  $ hg sparse --include 'show*'
  $ touch hide
  $ hg sparse --delete 'show*' --force -Tjson
  pending changes to 'hide'
