I lost it head failed me you want me copy more information text
from the actual commit??

No, it's just that your commit messages are not clear at all. You
mention that you remove something and point another commit without
any explanation about the link between them. I'm just proposing an
example of how to better explain the justification for your patch.

As a rule of thumb, when you propose a patch for inclusion, always
think that you're trying to sell it to someone else who will have
to take care of its consequences forever. So you must put all the
good arguments on it, just as if it was printed on the package of a
product. Of course here it's just a tiny doc patch but the principle
remains, the why and how still needs to be clear.

But I am still reluctant to bump up the version number and would like to sent
all the 4 patches AFRESH(which has nothing to do with the previous patchtes I
have sent) .

Who cares ? Is a version expensive in any way ? Is there any shame in
sending multiple versions ? Put yourself in the place of your recipients.
They receive 500-2000 emails a day, get yours possibly in a random order
if their connection is a bit flaky, and are not always perfectly sure
which ones are still relevant after some comments were emitted by others.
The version is just a simple way to say "ignore everything I sent before
this one". If you send a v3, it will be obvious that anything without any
version or marked v2 can safely be ignored.

In addition you say that you send a fresh series, but even that series was
very confusing, with patches having almost the same names more or less one
word ("stanza" vs "line") so it was not clear whether each patch was a new
attempt at fixing a typo in the previous one or for something different. A
version number clarifies that. And numbering the patches as well by the way.

Can I do that Willy???

You can do whatever you want. We all find the rules annoying when we have
to follow them but convenient from the recipient side. Thus it's just a
matter of whether or not you want to increase the chances that your patches
are caught by someone and merged. The more confusing they are, the less
likely someone will be willing to spend valuable time on them, and once
they're out of the visible window they're forgotten. I'd suggest that you
usually go the easy way first and once you get some reviews you need to
be careful to address them completely and accurately (or indicate your
disapproval and why).

AFAIK. I mean, the version bumping and provide information appended to every
other following mail. If that is significant then I understand ...but for this thing....I
hope you get me...

I'd say that for that trivial a patch it's probably not very useful,
just like it can be dropped in a fast round trip with a person on a
short topic. But when you get some reviews, reviewers never know if
you wrote the new series before, during or after their review, and not
knowing if you took their comments into consideration either makes
them hesitant to review again, or irritated seeing that they were not
considered yet. Just for this it's a good practice to mention what
comments were addressed here. It's just an Ack for the reviewers to
say "I tried to follow your advice, if it's still wrong, let me know".
For example Greg made some very precise comments about the format he
expected for the commit IDs, that apparently you still got wrong several
times. How can he know if you tried to address that and failed, or just
read it after sending ?


Hmmm ....okay...every words your wrote is absolutely right and that is how it
is been practicing here in this project.
I am not sure why the hell I deviated from that rule or practice.

My sincere apologies to everyone ,whoever getting my mail for this specific
patch series.

Look like we need someone good at sending patches proper way.
It seems, I am going to get into the "kill file" of lot of people ...meh ..heck

Keeping all the words in mind Yours and Greg's(Please don't fret) ..well another
hoorah at the patch making and send of this series. And I sincerely don't know
this time who bothers about my sending ....I do hope ..
