patchbomb: add a 'patchbomb.intro' option

This option allows the user to control the default behavior for
including an introduction message. This avoids having to tirelessly
skip the intro for people contributing to Mercurial.

The three possibles values are:
- always,
- auto (default, current behavior),
- never.

I was thinking of ("true", "false", "") (empty value being auto) but I ruled it
out as too confusing.

This new config option reuses the pre-existing 'patchbomb' section.

 '''command to send changesets as (a series of) patch emails
 
 The series is started off with a "[PATCH 0 of N]" introduction, which
 describes the series as a whole.
 
 Each patch email has a Subject line of "[PATCH M of N] ...", using the
 first line of the changeset description as the subject text. The
 message contains two or three body parts:
 
 - The changeset description.
 - [Optional] The result of running diffstat on the patch.
 - The patch itself, as generated by :hg:`export`.
 
 Each message refers to the first in the series using the In-Reply-To
 and References headers, so they will show up as a sequence in threaded
 mail and news readers, and in mail archives.
 
 To configure other defaults, add a section like this to your
 configuration file::
 
   [email]
   from = My Name <my@email>
   to = recipient1, recipient2, ...
   cc = cc1, cc2, ...
   bcc = bcc1, bcc2, ...
   reply-to = address1, address2, ...
 
 Use ``[patchbomb]`` as configuration section name if you need to
 override global ``[email]`` address settings.
 
 Then you can use the :hg:`email` command to mail a series of
 changesets as a patchbomb.
 
 You can also either configure the method option in the email section
 to be a sendmail compatible mailer or fill out the [smtp] section so
 that the patchbomb extension can automatically send patchbombs
 directly from the commandline. See the [email] and [smtp] sections in
 hgrc(5) for details.
+
+You can control the default inclusion of an introduction message with the
+``patchbomb.intro`` configuration option. The configuration is always
+overwritten by command line flags like --intro and --desc::
+
+  [patchbomb]
+  intro=auto   # include introduction message if more than 1 patch (default)
+  intro=never  # never include an introduction message
+  intro=always # always include an introduction message

     By default, diffs are sent in the format generated by
     :hg:`export`, one per message. The series starts with a "[PATCH 0
     of N]" introduction, which describes the series as a whole.
 
     Each patch email has a Subject line of "[PATCH M of N] ...", using
     the first line of the changeset description as the subject text.
     The message contains two or three parts. First, the changeset
     description.
 
     With the -d/--diffstat option, if the diffstat program is
     installed, the result of running diffstat on the patch is inserted.
 
     Finally, the patch itself, as generated by :hg:`export`.
 
     With the -d/--diffstat or --confirm options, you will be presented
     with a final summary of all messages and asked for confirmation before
     the messages are sent.
 
     By default the patch is included as text in the email body for
     easy reviewing. Using the -a/--attach option will instead create
     an attachment for the patch. With -i/--inline an inline attachment
     will be created. You can include a patch both as text in the email
     body and as a regular or an inline attachment by combining the
     -a/--attach or -i/--inline with the --body option.
 
     With -o/--outgoing, emails will be generated for patches not found
     in the destination repository (or only those which are ancestors
     of the specified revisions if any are provided)
 
     With -b/--bundle, changesets are selected as for --outgoing, but a
     single email containing a binary Mercurial bundle as an attachment
     will be sent.
 
     With -m/--mbox, instead of previewing each patchbomb message in a
     pager or sending the messages directly, it will create a UNIX
     mailbox file with the patch emails. This mailbox file can be
     previewed with any mail user agent which supports UNIX mbox
     files.
 
     With -n/--test, all steps will run, but mail will not be sent.
     You will be prompted for an email recipient address, a subject and
     an introductory message describing the patches of your patchbomb.
     Then when all is done, patchbomb messages are displayed. If the
     PAGER environment variable is set, your pager will be fired up once
     for each patchbomb message, so you can verify everything is alright.
 
     In case email sending fails, you will find a backup of your series
-    introductory message in ``.hg/last-email.txt``.
+    introductory message in ``.hg/last-email.txt``. The inclusion the
+    introduction can also be control using the ``patchbomb.intro`` option. (see
+    hg help patchbomb for details)
 
     Examples::
 
       hg email -r 3000          # send patch 3000 only
       hg email -r 3000 -r 3001  # send patches 3000 and 3001
       hg email -r 3000:3005     # send patches 3000 through 3005
       hg email 3000             # send patch 3000 (deprecated)
 
       hg email -o               # send all patches not in default
       hg email -o DEST          # send all patches not in DEST
       hg email -o -r 3000       # send all ancestors of 3000 not in default
       hg email -o -r 3000 DEST  # send all ancestors of 3000 not in DEST
 
       hg email -b               # send bundle of all patches not in default
       hg email -b DEST          # send bundle of all patches not in DEST
       hg email -b -r 3000       # bundle of all ancestors of 3000 not in default
       hg email -b -r 3000 DEST  # bundle of all ancestors of 3000 not in DEST
 
       hg email -o -m mbox &&    # generate an mbox file...
         mutt -R -f mbox         # ... and view it with mutt
       hg email -o -m mbox &&    # generate an mbox file ...
