V15 is wrongly threaded:
- Patch 2 has no In-Reply-To / In-Reply-To headers
- Patch 3 to 13 reference patch 2 instead of the cover letter
- Patch 14 has no In-Reply-To / In-Reply-To headers
- Patch 15 references patch 14 instead of the cover letter
- Patch 16 has no In-Reply-To / In-Reply-To headers
- Patch 17 to 23 reference patch 17 instead of the cover letter

Said otherwise, the patches appears as (sorry for the long lines):

I *think* it is the reason why some tools are not able to consider all
the patches as a single patchset.
