I will send v2 of the patch with a revised and more detailed
explanation about the behavior aspect of the patch.

Yep - did that just like the instructions on "SubmmitingPatches", unfortunately, although I've followed the Thunderbird configuration instructions
with external editor, it seems to sent the the email content wrong (bad line endings as I saw now).
