While we're on that subject, I'd much prefer if these technical docs and other asciidoc-ish stuff we would be manpages build as part of our normal "make doc" target. So e.g. this one would be readable via something like "man 3 gitapi-oid-array". They could still be maintained along with the code given a sufficiently smart doc build system, e.g. perl does that: https://github.com/Perl/perl5/blob/v5.26.0/av.c#L294-L387 Although doing that in some readable and sane way would mean getting rid of your beloved multi-line /* ... */ comment formatting, at least for that case. It would be a pain to have everyone configure their editor to word-wrap lines with leading "*" without screwing up the asciidoc format.
