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.

46 ====================== |
12828 | 47 |
48 If ``.hgsub`` does not exist, create it and add it to the parent | |
49 repository. Clone or checkout the external projects where you want it | |
50 to live in the parent repository. Edit ``.hgsub`` and add the | |
51 subrepository entry as described above. At this point, the | |
52 subrepository is tracked and the next commit will record its state in | |
53 ``.hgsubstate`` and bind it to the committed changeset. | |

56 ============================= |
12828 | 57 |
58 Subrepos do not automatically track the latest changeset of their | |
59 sources. Instead, they are updated to the changeset that corresponds | |
60 with the changeset checked out in the top-level changeset. This is so | |
61 developers always get a consistent set of compatible code and | |
62 libraries when they update. | |
63 | |
64 Thus, updating subrepos is a manual process. Simply check out target | |
65 subrepo at the desired revision, test in the top-level repo, then | |
66 commit in the parent repository to record the new combination. | |

137 A subrepository source location may change during a project life, | |

139 fix this, rewriting rules can be defined in parent repository ``hgrc`` | |
