add sequencial number in subject prefix

[tkikuchi]

This patch for 'CookHeaders.py' add an ability to add a
sequencial number in the subject prefix. You can define
a subject prefix like:
   [listname %d]
Then, the subject line of delivered mail becomes:
   Subject: [listname 123] Hoge hoge
When someone replied this mail, mailman receives a
messages with:
   Subject: Re: [listname 123] Hoge hoge
Then, this patch removes [listname \d+] part and
deliver it with:
   Subject: [listname 124] Re: Hoge hoge
And next, another person replies with
   Subject: Re: [listname 124] Re: Hoge hoge
Then, (magically!) you get:
   Subject: [listname 125] Re: Hoge hoge
Not with Re: Re: Hoge hoge.

Looks like complicated but this patch has been working
well with Japanese-enhanced Mailman for more than a year.

Without %d, this patch works like current version, I
believe.

I have uploaded the patch with the same name as the old one.
Please download the upper one because it's newer.
Sorry for the inconvenience.

If you need a quick fix to make the patch work with 2.1.1
here's my take (it's the diff file adapted to work with 2.1.1
CookHeaders.py)

Hi, I am pleased you like this patch.
Here is my current version attached.

update of patch for 2.1.1
if the subject is all ascii, then cat the prefix and subject
before it is instantiated. Hope to solve prefix only subject
1st line.

Note: with this patch without $d, Re: [prefix] is now
mungled to [prefix] Re:. This is useful if someone post new
issue as follow up to old subject like;
New subject bah bah was Re: [prefix] foo

sorry for daily update but there was an error in i18n
handling of '(no subject)'

Is there a version vor MM 2.1.2? I'm trying the older one but
doesn't seem to work.

Now the patch includes instruction in General admin page.
(in detail part). In source dir you should type:
patch -p0 < /path/to/seqnum.patch

[tkikuchi (tkikuchi-users)]

This patch for 2.1.3 is also applicable to 2.1.4. Though one
patch fails to apply, it can safely be neglected. You can
also get a newer and more convenient patch at:

Hi tkikuchi,

There are some gibberish text within the patch, are they
Japanesh chars..??

If possible can you look at this tracker and give your
suggestions.https://sourceforge.net/tracker/index.php?func=detail&aid=1024289&group_id=103&atid=300103

This is basically I want to implement threading in Mailman.
Yes Mailman implements threading I agree but when the mail
replies are sent using Lotus Notes 5.0.8/5.0.9 the threading
doesn't work because Lotus Notes doesn't set the
"In-Reply-To" header.

Thanks for your time
