Hi,

that's not the way you would like it to work.
It happens that some maintainers make some small adjustments in the 
commit message or the patch itself.

The patch is good enough for me. If you can not accept the additional 
small clean-up, or don't have time to tweak it by yourself, or by anyone 
else, please, just reject it.
The issue I propose to fix is minor and unlikely to happen anyway.

If anyone else cares to update the proposal, please do.


I don't want to discuss your motivation, I understand them.

But please, do also understand mine and do not require too futile things 
from hobbyists.

Spending time only to remove a CR because it does not match your quality 
standard or your expectation of what a patch is, is of no interest for me.
That's why I told I would not send a V2.


It is up to you to accept it as-is, update it or reject it, according to 
the value you think this patch has.

Hoping for your understanding and sorry for wasting your time.

Best regards,
CJ
