pathencode: skip encoding if input is already longer than maxstorepathlen

Calling basicencode may make the path longer, never shorter. If it's already
too long before, then we don't even need to basicencode it.

Moving bookmarks, preserve active bookmark:

  $ hg book book2
  $ hg ci --amend -m 'move bookmarks'

   * book2                     1:7344472bd951

  $ echo '[defaults]' >> $HGRCPATH
  $ echo "commit=-d '0 0'" >> $HGRCPATH

Moving branches:

  $ hg branch foo
  marked working directory as branch foo
  (branches are permanent and global, did you want a bookmark?)
  $ echo a >> a
  $ hg ci -m 'branch foo'
  $ hg branch default -f
  marked working directory as branch default
  (branches are permanent and global, did you want a bookmark?)
  $ hg ci --amend -m 'back to default'
  saved backup bundle to $TESTTMP/.hg/strip-backup/1661ca36a2db-amend-backup.hg (glob)
  $ hg branches
  default                        2:f24ee5961967

Close branch:

  $ hg up -q 0
  $ echo b >> b
  $ hg branch foo
  marked working directory as branch foo
  (branches are permanent and global, did you want a bookmark?)
  $ hg ci -Am 'fork'
  adding b
  $ echo b >> b
  $ hg ci -mb
  $ hg ci --amend --close-branch -m 'closing branch foo'
  saved backup bundle to $TESTTMP/.hg/strip-backup/c962248fa264-amend-backup.hg (glob)

Same thing, different code path:

  $ echo b >> b
  $ hg ci -m 'reopen branch'
  reopening closed branch head 4
  $ echo b >> b
  $ hg ci --amend --close-branch
  saved backup bundle to $TESTTMP/.hg/strip-backup/5e302dcc12b8-amend-backup.hg (glob)
  $ hg branches
  default                        2:f24ee5961967

Refuse to amend merges:

  $ hg up -q default
  $ hg merge foo
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci --amend
  abort: cannot amend while merging
  [255]
  $ hg ci -m 'merge'
  $ hg ci --amend
  abort: cannot amend merge changesets
  [255]

Follow copies/renames:

  $ hg mv b c
  $ hg ci -m 'b -> c'
  $ hg mv c d
  $ hg ci --amend -m 'b -> d'
  saved backup bundle to $TESTTMP/.hg/strip-backup/9c207120aa98-amend-backup.hg (glob)
  $ hg st --rev '.^' --copies d
  A d
    b
  $ hg cp d e
  $ hg ci -m 'e = d'
  $ hg cp e f
  $ hg ci --amend -m 'f = d'
  saved backup bundle to $TESTTMP/.hg/strip-backup/fda2b3b27b22-amend-backup.hg (glob)
  $ hg st --rev '.^' --copies f
  A f
    d

  $ mv f f.orig
  $ hg rm -A f
  $ hg ci -m removef
  $ hg cp a f
  $ mv f.orig f
  $ hg ci --amend -m replacef
  saved backup bundle to $TESTTMP/.hg/strip-backup/20a7413547f9-amend-backup.hg (glob)
  $ hg st --change . --copies
  $ hg log -r . --template "{file_copies}\n"
  

Move added file (issue3410):

  $ echo g >> g
  $ hg ci -Am g
  adding g
  $ hg mv g h
  $ hg ci --amend
  saved backup bundle to $TESTTMP/.hg/strip-backup/5daa77a5d616-amend-backup.hg (glob)
  $ hg st --change . --copies h
  A h
  $ hg log -r . --template "{file_copies}\n"
  

Can't rollback an amend:

  $ hg rollback
  no rollback information available
  [1]

Preserve extra dict (issue3430):

  $ hg branch a
  marked working directory as branch a
  (branches are permanent and global, did you want a bookmark?)
  $ echo a >> a
  $ hg ci -ma
  $ hg ci --amend -m "a'"
  saved backup bundle to $TESTTMP/.hg/strip-backup/167f8e3031df-amend-backup.hg (glob)
  $ hg log -r . --template "{branch}\n"
  a
  $ hg ci --amend -m "a''"
  saved backup bundle to $TESTTMP/.hg/strip-backup/ceac1a44c806-amend-backup.hg (glob)
  $ hg log -r . --template "{branch}\n"
  a

Also preserve other entries in the dict that are in the old commit,
first graft something so there's an additional entry:

  $ hg up 0 -q
  $ echo z > z
  $ hg ci -Am 'fork'
  adding z
  created new head
  $ hg up 11
  5 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg graft 12
  grafting revision 12
  $ hg ci --amend -m 'graft amend'
  saved backup bundle to $TESTTMP/.hg/strip-backup/18a5124daf7a-amend-backup.hg (glob)
  $ hg log -r . --debug | grep extra
  extra:       branch=a
  extra:       source=2647734878ef0236dda712fae9c1651cf694ea8a

Preserve phase

  $ hg phase '.^::.'
  11: draft
  13: draft
  $ hg phase --secret --force .
  $ hg phase '.^::.'
  11: draft
  13: secret
  $ hg commit --amend -m 'amend for phase' -q
  $ hg phase '.^::.'
  11: draft
  13: secret

Test amend with obsolete
---------------------------

Enable obsolete

  $ cat > ${TESTTMP}/obs.py << EOF
  > import mercurial.obsolete
  > mercurial.obsolete._enabled = True
  > EOF
  $ echo '[extensions]' >> $HGRCPATH
  $ echo "obs=${TESTTMP}/obs.py" >> $HGRCPATH

Amend with files changes

ride of)
