doc: unify section level between help topics

Some help topics use "-" for the top level underlining section mark,
but "-" is used also for the top level categorization in generated
documents: "hg.1.html", for example.

So, TOC in such documents contain "sections in each topics", too.

This patch changes underlining section mark in some help topics to
unify section level in generated documents.

After this patching, levels of each section marks are:

  level0
  """"""
    level1
    ======
      level2
      ------
        level3
        ......
          level4
          ######

And use of section markers in each documents are:

  - mercurial/help/*.txt can use level1 or more
    (now these use level1 and level2)

  - help for core commands can use level2 or more
    (now these use no section marker)

  - descriptions of extensions can use level2 or more
    (now hgext/acl uses level2)

  - help for commands defined in extension can use level4 or more
    (now "convert" of hgext/convert uses level4)

"Level0" is used as top level categorization only in "doc/hg.1.txt"
and the intermediate file generated by "doc/gendoc.py", so end users
don't see it in "hg help" outoput and so on.

Rebasing
D onto H - simple rebase:

  $ hg clone -q -u . a a1
  $ cd a1

  $ hg tglog
  @  7: 'H'
  |
  | o  6: 'G'
  |/|
  o |  5: 'F'
  | |
  | o  4: 'E'
  |/
  | o  3: 'D'
  | |
  | o  2: 'C'
  | |
  | o  1: 'B'
  |/
  o  0: 'A'
  

  $ hg rebase -s 3 -d 7
  saved backup bundle to $TESTTMP/a1/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @  7: 'D'
  |
  o  6: 'H'
  |
  | o  5: 'G'
  |/|
  o |  4: 'F'
  | |
  | o  3: 'E'
  |/
  | o  2: 'C'
  | |
  | o  1: 'B'
  |/
  o  0: 'A'
  
  $ cd ..


D onto F - intermediate point:

  $ hg clone -q -u . a a2
  $ cd a2

  $ hg rebase -s 3 -d 5
  saved backup bundle to $TESTTMP/a2/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @  7: 'D'
  |
  | o  6: 'H'
  |/
  | o  5: 'G'
  |/|
  o |  4: 'F'
  | |
  | o  3: 'E'
  |/
  | o  2: 'C'
  | |
  | o  1: 'B'
  |/
  o  0: 'A'
  
  $ cd ..


E onto H - skip of G:

  $ hg clone -q -u . a a3
  $ cd a3

  $ hg rebase -s 4 -d 7
  saved backup bundle to $TESTTMP/a3/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @  6: 'E'
  |
  o  5: 'H'
  |
  o  4: 'F'
  |
  | o  3: 'D'
  | |
  | o  2: 'C'
  | |
  | o  1: 'B'
  |/
  o  0: 'A'
  
  $ cd ..


F onto E - rebase of a branching point (skip G):

  $ hg clone -q -u . a a4
  $ cd a4

  $ hg rebase -s 5 -d 4
  saved backup bundle to $TESTTMP/a4/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @  6: 'H'
  |
  o  5: 'F'
  |
  o  4: 'E'

  | |
  | o  2: 'C'
  | |
  | o  1: 'B'
  |/
  o  0: 'A'
  
  $ cd ..


G onto H - merged revision having a parent in ancestors of target:

  $ hg clone -q -u . a a5
  $ cd a5

  $ hg rebase -s 6 -d 7
  saved backup bundle to $TESTTMP/a5/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @    7: 'G'
  |\
  | o  6: 'H'
  | |
  | o  5: 'F'
  | |
  o |  4: 'E'
  |/
  | o  3: 'D'
  | |
  | o  2: 'C'
  | |
  | o  1: 'B'
  |/
  o  0: 'A'
  
  $ cd ..


F onto B - G maintains E as parent:

  $ hg clone -q -u . a a6
  $ cd a6

  $ hg rebase -s 5 -d 1
  saved backup bundle to $TESTTMP/a6/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @  7: 'H'
  |
  | o  6: 'G'
  |/|
  o |  5: 'F'
  | |
  | o  4: 'E'
  | |
  | | o  3: 'D'
  | | |
  +---o  2: 'C'
  | |
  o |  1: 'B'
  |/
  o  0: 'A'
  
  $ cd ..


These will fail (using --source):

G onto F - rebase onto an ancestor:

  $ hg clone -q -u . a a7
  $ cd a7

  $ hg rebase -s 6 -d 5
  nothing to rebase
  [1]

F onto G - rebase onto a descendant:

  $ hg rebase -s 5 -d 6
  abort: source is ancestor of destination
  [255]

G onto B - merge revision with both parents not in ancestors of target:

  $ hg rebase -s 6 -d 1
  abort: cannot use revision 6 as base, result would have 3 parents
  [255]


These will abort gracefully (using --base):

G onto G - rebase onto same changeset:

  $ hg rebase -b 6 -d 6
  nothing to rebase
  [1]

G onto F - rebase onto an ancestor:

  $ hg rebase -b 6 -d 5
  nothing to rebase
  [1]

F onto G - rebase onto a descendant:

  $ hg rebase -b 5 -d 6
  nothing to rebase
  [1]

C onto A - rebase onto an ancestor:

  $ hg rebase -d 0 -s 2
  saved backup bundle to $TESTTMP/a7/.hg/strip-backup/5fddd98957c8-backup.hg (glob)
  $ hg tglog
  @  7: 'D'
  |
  o  6: 'C'
  |
  | o  5: 'H'
  | |
  | | o  4: 'G'
  | |/|
  | o |  3: 'F'
  |/ /
  | o  2: 'E'
  |/
  | o  1: 'B'
  |/
  o  0: 'A'
  

Check rebasing public changeset

  $ hg pull --config phases.publish=True -q -r 6 . # update phase of 6
  $ hg rebase -d 5 -b 6
  abort: can't rebase immutable changeset e1c4361dd923
  (see hg help phases for details)
  [255]

  $ hg rebase -d 5 -b 6 --keep

Check rebasing mutable changeset
Source phase greater or equal to destination phase: new changeset get the phase of source:
  $ hg rebase -s9 -d0
  saved backup bundle to $TESTTMP/a7/.hg/strip-backup/2b23e52411f4-backup.hg (glob)
  $ hg log --template "{phase}\n" -r 9
  draft
  $ hg rebase -s9 -d1
  saved backup bundle to $TESTTMP/a7/.hg/strip-backup/2cb10d0cfc6c-backup.hg (glob)
  $ hg log --template "{phase}\n" -r 9
  draft
  $ hg phase --force --secret 9
  $ hg rebase -s9 -d0
  saved backup bundle to $TESTTMP/a7/.hg/strip-backup/c5b12b67163a-backup.hg (glob)
  $ hg log --template "{phase}\n" -r 9

  $ hg rebase -s9 -d1
  saved backup bundle to $TESTTMP/a7/.hg/strip-backup/2a0524f868ac-backup.hg (glob)
  $ hg log --template "{phase}\n" -r 9
  secret
Source phase lower than destination phase: new changeset get the phase of destination:
  $ hg rebase -s8 -d9
  saved backup bundle to $TESTTMP/a7/.hg/strip-backup/6d4f22462821-backup.hg (glob)
  $ hg log --template "{phase}\n" -r 'rev(9)'
  secret

  $ cd ..

Test for revset

We need a bit different graph
All destination are B

  $ hg init ah
  $ cd ah
  $ hg unbundle "$TESTDIR/bundles/rebase-revset.hg"
  adding changesets
  adding manifests
  adding file changes
  added 9 changesets with 9 changes to 9 files (+2 heads)
  (run 'hg heads' to see heads, 'hg merge' to merge)
  $ hg tglog
  o  8: 'I'
  |
  o  7: 'H'
  |
  o  6: 'G'
  |
  | o  5: 'F'

  | o  4: 'E'

Simple case with keep:

Source on have two descendant heads but ask for one

  $ hg clone -q -u . ah ah1
  $ cd ah1
  $ hg rebase -r '2::8' -d 1
  abort: can't remove original changesets with unrebased descendants
  (use --keep to keep original changesets)
  [255]
  $ hg rebase -r '2::8' -d 1 --keep
  $ hg tglog
  @  13: 'I'
  |
  o  12: 'H'
  |
  o  11: 'G'
  |
  o  10: 'D'
  |
  o  9: 'C'
  |
  | o  8: 'I'
  | |
  | o  7: 'H'

  | o  6: 'G'

  | | o  5: 'F'

  | o  2: 'C'

  o |  1: 'B'

  o  0: 'A'
  

  $ cd ..

Base on have one descendant heads we ask for but common ancestor have two

  $ hg clone -q -u . ah ah2
  $ cd ah2
  $ hg rebase -r '3::8' -d 1
  abort: can't remove original changesets with unrebased descendants
  (use --keep to keep original changesets)

  $ hg rebase -r '3::8' -d 1 --keep

rebase subset

  $ hg clone -q -u . ah ah3

  | o  2: 'C'

  o |  1: 'B'
  |/
  o  0: 'A'
  

  $ cd ..

rebase subset with multiple head

  $ hg clone -q -u . ah ah4
  $ cd ah4
  $ hg rebase -r '3::(7+5)' -d 1
  abort: can't remove original changesets with unrebased descendants

More advanced tests

rebase on ancestor with revset

  $ hg clone -q -u . ah ah5
  $ cd ah5
  $ hg rebase -r '6::' -d 2
  saved backup bundle to $TESTTMP/ah5/.hg/strip-backup/3d8a618087a7-backup.hg (glob)

rebase with multiple root.
We rebase E and G on B
We would expect heads are I, F if it was supported

  $ hg clone -q -u . ah ah6
  $ cd ah6
  $ hg rebase -r '(4+6)::' -d 1
  abort: can't rebase multiple roots
  [255]
  $ cd ..
