create another commit

  $ echo n > n

shelve a change that we will delete later

  $ echo a >> a/a
  $ hg shelve

set up some more complex changes to shelve

  $ echo a >> a/a

  $ hg cp c c.copy
  $ hg status -C
  M a/a

prevent some foot-shooting

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

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

ensure that our shelved changes exist

  $ hg shelve -l

named shelves, specific filenames, and "commit messages" should all work

  A c.copy
    c
  R b/b
  $ hg shelve -q -n wibble -m wat a

expect "a" to no longer be present, but status otherwise unchanged

  $ hg status -C

  R b/b
  $ hg shelve -l --stat
  wibble          (*)    wat (glob)
   a/a |  1 +
   1 files changed, 1 insertions(+), 0 deletions(-)

and now "a/a" should reappear

  $ hg unshelve -q wibble
  $ hg status -C
  M a/a
  A b.rename/b
    b/b
  A c.copy

add an unrelated change that should be preserved
