Thanks for reworking this patch with links to the upstream commits!

However the above changes to curl docs seems to be triggering
reproducibility errors in the docs package:

https://autobuilder.yocto.io/pub/repro-fail/oe-reproducible-20230313-ef21ejrc/packages/diff-html/

This may be an issue that has been lurking un-noticed, but just
finally triggered by this change.

However it also does raise the issue of whether we should be patching
the docs for 7.82 with text claiming "Added in 7.88.0"

Thoughts?
