This make the code simpler and will make it simpler to add more case in the
future.

Shelve and unshelve unknown files. For the purposes of unshelve, a shelved
unknown file is the same as a shelved added file, except that it will be in
unknown state after unshelve if and only if it was either absent or unknown
before the unshelve operation.

  $ hg init unknowns
  $ cd unknowns

The simplest case is if I simply have an unknown file that I shelve and unshelve

  $ echo unknown > unknown
  $ hg status
  ? unknown
  $ hg shelve --unknown
  shelved as default
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg status
  $ hg unshelve
  unshelving change 'default'
  $ hg status
  ? unknown
  $ rm unknown

If I shelve, add the file, and unshelve, does it stay added?

  $ echo unknown > unknown
  $ hg shelve -u
  shelved as default
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg status
  $ touch unknown
  $ hg add unknown
  $ hg status
  A unknown
  $ hg unshelve
  unshelving change 'default'
  temporarily committing pending changes (restore with 'hg unshelve --abort')
  rebasing shelved changes
  merging unknown
  $ hg status
  A unknown
  $ hg forget unknown
  $ rm unknown

And if I shelve, commit, then unshelve, does it become modified?

  $ echo unknown > unknown
  $ hg shelve -u
  shelved as default
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg status
  $ touch unknown
  $ hg add unknown
  $ hg commit -qm "Add unknown"
  $ hg status
  $ hg unshelve
  unshelving change 'default'
  rebasing shelved changes
  merging unknown
  $ hg status
  M unknown
  $ hg remove --force unknown
  $ hg commit -qm "Remove unknown"

  $ cd ..

We expects that non-bare shelve keeps newly created branch in
working directory.

  $ hg init shelve-preserve-new-branch
  $ cd shelve-preserve-new-branch
  $ echo "a" >> a
  $ hg add a
  $ echo "b" >> b
  $ hg add b
  $ hg commit -m "ab"
  $ echo "aa" >> a
  $ echo "bb" >> b
  $ hg branch new-branch
  marked working directory as branch new-branch
  (branches are permanent and global, did you want a bookmark?)
  $ hg status
  M a
  M b
  $ hg branch
  new-branch
  $ hg shelve a
  shelved as default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg branch
  new-branch
  $ hg status
  M b
  $ touch "c" >> c
  $ hg add c
  $ hg status
  M b
  A c
  $ hg shelve --exclude c
  shelved as default-01
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg branch
  new-branch
  $ hg status
  A c
  $ hg shelve --include c
  shelved as default-02
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg branch
  new-branch
  $ hg status
  $ echo "d" >> d
  $ hg add d
  $ hg status
  A d

We expect that bare-shelve will not keep branch in current working directory.

  $ hg shelve
  shelved as default-03
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg branch
  default
  $ cd ..

When i shelve commit on newly created branch i expect
that after unshelve newly created branch will be preserved.

  $ hg init shelve_on_new_branch_simple
  $ cd shelve_on_new_branch_simple
  $ echo "aaa" >> a
  $ hg commit -A -m "a"
  adding a
  $ hg branch
  default
  $ hg branch test
  marked working directory as branch test
  (branches are permanent and global, did you want a bookmark?)
  $ echo "bbb" >> a
  $ hg status
  M a
  $ hg shelve
  shelved as default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg branch
  default
  $ echo "bbb" >> b
  $ hg status
  ? b
  $ hg unshelve
  unshelving change 'default'
  marked working directory as branch test
  $ hg status
  M a
  ? b
  $ hg branch
  test
  $ cd ..

When i shelve commit on newly created branch, make
some changes, unshelve it and running into merge
conflicts i expect that after fixing them and
running unshelve --continue newly created branch
will be preserved.

  $ hg init shelve_on_new_branch_conflict
  $ cd shelve_on_new_branch_conflict
  $ echo "aaa" >> a
  $ hg commit -A -m "a"
  adding a
  $ hg branch

  [240]
  $ echo "aaabbbccc" > a
  $ rm a.orig
  $ hg resolve --mark a
  (no more unresolved files)
  continue: hg unshelve --continue
  $ hg continue
  marked working directory as branch test
  unshelve of 'default' complete
  $ cat a
  aaabbbccc
  $ hg status
  M a
  $ hg branch
  test
  $ hg commit -m "test-commit"

When i shelve on test branch, update to default branch
and unshelve i expect that it will not preserve previous
test branch.

  $ echo "xxx" > b
  $ hg add b
  $ hg shelve
  shelved as test
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg update -r 7049e48789d7
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg unshelve
  unshelving change 'test'
  rebasing shelved changes
  $ hg status
  A b
  $ hg branch
  default
  $ cd ..

When i unshelve resulting in merge conflicts and makes saved
file shelvedstate looks like in previous versions in
mercurial(without restore branch information in 7th line) i
expect that after resolving conflicts and successfully
running 'shelve --continue' the branch information won't be
restored and branch will be unchanged.

shelve on new branch, conflict with previous shelvedstate

  $ hg init conflict
  $ cd conflict
  $ echo "aaa" >> a
  $ hg commit -A -m "a"
  adding a
  $ hg branch
  default
  $ hg branch test
  marked working directory as branch test

  unresolved conflicts (see 'hg resolve', then 'hg unshelve --continue')
  [240]

Removing restore branch information from shelvedstate file(making it looks like
in previous versions) and running unshelve --continue

  $ cp .hg/shelvedstate .hg/shelvedstate_old
  $ cat .hg/shelvedstate_old | grep -v 'branchtorestore' > .hg/shelvedstate

  $ echo "aaabbbccc" > a
  $ rm a.orig
  $ hg resolve --mark a
  (no more unresolved files)
  continue: hg unshelve --continue

#if continuecommand
  $ hg continue --dry-run
  unshelve in progress, will be resumed
#endif

  $ hg continue
  unshelve of 'default' complete
  $ cat a
  aaabbbccc
  $ hg status
  M a
  $ hg branch
  default
  $ cd ..

On non bare shelve the branch information shouldn't be restored

  $ hg init bare_shelve_on_new_branch
  $ cd bare_shelve_on_new_branch
  $ echo "aaa" >> a
  $ hg commit -A -m "a"
