doc: show short description of each commands in generated documents
Before this patch, short description of each commands is not shown in
generated documents (HTML file and UNIX man page). This omitting may
prevent users from understanding about commands.
This patch show it as the 1st paragraph in the help section of each
commands. This style is chosen because:
- showing it as the section title in "command - short desc" style
disallows referencing by "#command" in HTML file: in "en" locale,
hyphen concatenated title is used as the section ID in HTML file
for this style
- showing it as the 1st paragraph in "command - short desc" style
seems to be redundant: "command" appears also just before as the
section title
- showing it just after synopsis like "hg help command" seems not to
be reasonable in UNIX man page
This patch just writes short description ("d['desc'][0]") before "::",
because it should be already "strip()"-ed in "get_desc()", or empty
string for the command without description.

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

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

136 ================================= |

138 A subrepository source location may change during a project life, | |
139 invalidating references stored in the parent repository history. To | |
140 fix this, rewriting rules can be defined in parent repository ``hgrc`` | |
141 file or in Mercurial configuration. See the ``[subpaths]`` section in | |
142 hgrc(5) for more details. | |
