test-merge5: removed unnecessary parts of test
- no need to initialize a new directory
- no need to fix the commit time, already done by run-tests
- no need to exit 0, use exit code from hg instead
- better spacing around comments

'''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.
With the -d/--diffstat option, you will be prompted for each changeset
with a diffstat summary and the changeset summary, so you can be sure
you are sending the right changes.
To configure other defaults, add a section like this to your hgrc
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.
To avoid sending patches prematurely, it is a good idea to first run
the :hg:`email` command with the "-n" option (test only). 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.
The -m/--mbox option is also very useful. 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, e.g. with mutt::
% mutt -R -f mbox
When you are previewing the patchbomb messages, you can use ``formail``
(a utility that is commonly installed as part of the procmail
package), to send each message out::
% formail -s sendmail -bm -t < mbox
That should be all. Now your patchbomb is on its way out.
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.

'''send changesets by email
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. Next, (optionally) if the diffstat program is
installed and -d/--diffstat is used, the result of running
diffstat on the patch. Finally, the patch itself, as generated by
:hg:`export`.
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.
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.
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
Before using this command, you will need to enable email in your
hgrc. See the [email] section in hgrc(5) for details.
