Email subject line formatting

[David Holmes]

Hi everyone,

Erik asked me to raise this here to see if anyone else is bothered by 
this ...

When an integration email is sent the subject line of the RFR thread is 
augmented with [integrated] and also adorned with "Re:" as if a reply to 
the RFR thread e.g.

Re: [Integrated] [foreign-abi] RFR: Revert "JDK-8242127: reorganize 
ABI-dependent layout constants"

My objection to this is that once the subject has been augmented with 
[Integrated] it is not appropriate to treat that as a "reply" and use 
the "Re:". If I see:

[Integrated] [foreign-abi] RFR: Revert "JDK-8242127: reorganize 
ABI-dependent layout constants"

I know its a changeset notification email and I can ignore it. Just as I 
can ignore:

git: openjdk/panama-foreign: foreign-jextract: 2 new changesets

or

hg: jdk/jdk: 8242217: Shenandoah: Enable GC mode to be 
diagnostic/experimental and have a name

but when I see the "Re:" I think "oh someone is commenting on that push, 
there must be an issue and I should read the email" - which is the case 
with current hg notification emails!

This would be less of an issue if the sender of the integration email 
was a bot account but it isn't, it is the committer.

So I'd like to suggest that the "Re:" be dropped from the subject line 
of these automatically generated integration emails.

Cheers,
David
