Make status look into subrepositories by default:

  $ echo '[defaults]' >> $HGRCPATH

  $ echo 'status = -S' >> $HGRCPATH

  $ echo 'diff = --nodates -S' >> $HGRCPATH

Create test repository:

  $ hg init

  $ echo x1 > x.txt

  $ hg add x.txt

  $ hg init foo

  $ cd foo

  $ echo y1 > y.txt

  $ hg add y.txt

  $ hg init bar

  $ cd bar

  $ echo z1 > z.txt

  $ hg add z.txt

  $ cd ..

  $ echo 'bar = bar' > .hgsub

  $ hg add .hgsub

  $ cd ..

  $ echo 'foo = foo' > .hgsub

  $ hg add .hgsub

Test recursive status without committing anything:

  $ hg status

  A .hgsub

  A foo/.hgsub

  A foo/bar/z.txt

  A foo/y.txt

  A x.txt

Test recursive diff without committing anything:

  $ hg diff foo

  diff -r 000000000000 foo/.hgsub

  --- /dev/null
