shelve: be quiet when unshelve pulls from the shelve bundle

unshelve was quite verbose and it was hard for a user to follow what really was
going on. It ended up saying 'added 1 changesets' ... but the user just
expected and got pending changes and never saw any changeset.

The use of bundles is an implementation detail that we don't have to leak here.

Pulling is quite verbose, optimized for pulling many changesets from remote
repos - that is not the case here.

Instead, set the quiet flag when pulling the bundle - not only when temporarily
committing pending changes.

The 'finally' restore of ui.quiet is moved to the outer try/finally used for
locking.

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
    c
  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
  default-01      (*)    changes to '[mq]: second.patch' (glob)
  default         (*)    changes to '[mq]: second.patch' (glob)

  $ hg shelve -l -p default
  default         (*)    changes to '[mq]: second.patch' (glob)

delete our older shelved change

  $ hg shelve -d default
  $ hg qfinish -a -q

local edits should not prevent a shelved change from applying

  $ printf "z\na\n" > a/a
  $ hg unshelve --keep
  unshelving change 'default-01'
  merging a/a

  $ hg revert --all -q
  $ rm a/a.orig b.rename/b c.copy

apply it and make sure our state is as expected

  $ hg unshelve

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

  $ hg shelve -l

  $ hg unshelve
  abort: no shelved changes to apply!
  [255]
  $ hg unshelve foo
  abort: shelved change 'foo' not found
  [255]

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

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

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

cause unshelving to result in a merge with 'a' conflicting

  $ hg shelve -q
  $ echo c>>a/a
  $ hg commit -m second
  $ hg tip --template '{files}\n'
  a/a

add an unrelated change that should be preserved

  $ mkdir foo
  $ echo foo > foo/foo
  $ hg add foo/foo

force a conflicted merge to occur
