Those URLs are unstable - simply naming the document properly in the commit
message so that a search engine can find it is enough.
Ack, I'll do it all over the place in this series (commit descriptions,
code comment blocks, etc.).

Merge this patch with the patch where those are used - no need for a separate
patch.

patches, but now I agree that it no longer makes sense since I have
reworked almost every patch in this series. I'm going to incorporate
them!
Thanks,
Stefano
