shelving in an empty repo should be possible

  $ hg shelve
  shelved as default
  0 files updated, 0 files merged, 5 files removed, 0 files unresolved

  $ hg unshelve
  unshelving change 'default'

  $ hg commit -q -m 'initial commit'

  $ hg shelve
  nothing changed
  [1]

create an mq patch - shelving should work fine with a patch applied

  $ echo n > n
  $ hg add n
  $ hg commit n -m second
  $ hg qnew second.patch

shelve a change that we will delete later

  $ echo a >> a/a
  $ hg shelve
  shelved as default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

set up some more complex changes to shelve

  $ echo a >> a/a
  $ hg mv b b.rename
  moving b/b to b.rename/b (glob)
  $ hg cp c c.copy
  $ hg status -C
  M a/a
  A b.rename/b
    b/b
  A c.copy

  R b/b

prevent some foot-shooting

  $ hg shelve -n foo/bar
  abort: shelved change names may not contain slashes
  [255]
  $ hg shelve -n .baz
  abort: shelved change names may not start with '.'
  [255]

the common case - no options or filenames

  $ hg shelve
  shelved as default-01
  2 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ hg status -C

ensure that our shelved changes exist

  $ hg shelve -l
