large-files: use a `changing_files` context when initializing the dirstate

We are obviously mutating the dirstate, so lets scope this mutation.

  $ cat >> $HGRCPATH <<EOF

  > pdiff = sh "$RUNTESTDIR/pdiff"
  > EOF

Create a repo with some stuff in it:

  $ hg init a
  $ cd a
  $ echo a > a
  $ echo a > d
  $ echo a > e
  $ hg ci -qAm0
  $ echo b > a
  $ hg ci -m1 -u bar
  $ hg mv a b
  $ hg ci -m2
  $ hg cp b c
  $ hg ci -m3 -u baz
  $ echo b > d
  $ echo f > e
  $ hg ci -m4
  $ hg up -q 3
  $ echo b > e
  $ hg branch -q stable
  $ hg ci -m5
  $ hg merge -q default --tool internal:local # for conflicts in e, choose 5 and ignore 4
  $ hg branch -q default
  $ hg ci -m6
  $ hg phase --public 3
  $ hg phase --force --secret 6

  $ hg log -G --template '{author}@{rev}.{phase}: {desc}\n'

Test --base for grafting the merge of 4 from the perspective of 5, thus only getting the change to d

  $ hg up -cqr 3
  $ hg graft -r 6 --base 5
  grafting 6:25a2b029d3ae "6" (tip)
  merging e
  $ hg st --change .
  M d

  $ hg -q strip . --config extensions.strip=

Test --base for collapsing changesets 2 and 3, thus getting both b and c

  $ hg up -cqr 0
  $ hg graft -r 3 --base 1
  grafting 3:4c60f11aa304 "3"
  merging a and b to b
  merging a and c to c
  $ hg st --change .
  A b
  A c
  R a

  $ hg -q strip . --config extensions.strip=

Specifying child as --base revision fails safely (perhaps slightly confusing, but consistent)

  $ hg graft -r 2 --base 3
  grafting 2:5c095ad7e90f "2"
  note: possible conflict - c was deleted and renamed to:
   a
  note: graft of 2:5c095ad7e90f created no changes to commit

Can't continue without starting:

  $ hg -q up -cr tip
  $ hg rm -q e
  $ hg graft --continue
  abort: no graft in progress
  [20]
  $ hg revert -r . -q e

Need to specify a rev:

  $ hg graft
  abort: no revisions specified
  [10]

Can't graft ancestor:

  $ hg graft 1 2
  skipping ancestor revision 1:5d205f8b35b6
  skipping ancestor revision 2:5c095ad7e90f
  [255]

Specify revisions with -r:

  $ hg graft -r 1 -r 2
  skipping ancestor revision 1:5d205f8b35b6
  skipping ancestor revision 2:5c095ad7e90f
  [255]

  $ hg graft -r 1 2
  warning: inconsistent use of --rev might give unexpected revision ordering!
  skipping ancestor revision 2:5c095ad7e90f
  skipping ancestor revision 1:5d205f8b35b6
  [255]

Conflicting date/user options:

  $ hg up -q 0
  $ hg graft -U --user foo 2
  abort: cannot specify both --user and --currentuser
  [10]
  $ hg graft -D --date '0 0' 2
  abort: cannot specify both --date and --currentdate
  [10]

Can't graft with dirty wd:

  $ hg up -q 0
  $ echo foo > a
  $ hg graft 1
  abort: uncommitted changes
  [20]
  $ hg revert a

Graft a rename:
(this also tests that editor is invoked if '--edit' is specified)

  $ hg status --rev "2^1" --rev 2
  A b
  R a
  $ HGEDITOR=cat hg graft 2 -u foo --edit
  grafting 2:5c095ad7e90f "2"
  merging a and b to b

  HG: Enter commit message.  Lines beginning with 'HG:' are removed.
  HG: Leave message empty to abort commit.
  HG: --
  HG: user: foo

Commit while interrupted should fail:

  $ hg ci -m 'commit interrupted graft'
  abort: graft in progress
  (use 'hg graft --continue' or 'hg graft --stop' to stop)
  [20]

Abort the graft and try committing:

  $ hg up -C .

  $ echo c >> e
  $ hg ci -mtest

  $ hg strip . --config extensions.strip=

  abort: unresolved merge conflicts (see 'hg help resolve')
  [20]

Fix up:

  $ echo b > e
  $ hg resolve -m e
  (no more unresolved files)
  continue: hg graft --continue

Continue with a revision should fail:

  $ hg graft -c 6
  abort: can't specify --continue and revisions
