So whenever asciidoctor diverges, it looks like a bug. This is indeed the case. Asciidoctor is a bit stricter on some inputs because it provides significant performance improvements, but it also has features that AsciiDoc does not. It also has some bugs that AsciiDoc does not (again, usually due to performance concerns). For example, Debian's reproducible builds project would probably like it if we had better support for Asciidoctor. > [1] I think we've also traditionally considered asciidoc to be the > definitive toolchain, and people using asciidoctor are free to > submit patches to make things work correctly in both places.

I'll see if I can come up with some patches based on Dscho's work. -- brian m. carlson / brian with sandals: Houston, Texas, US +1 832 623 2791 | https://www.crustytoothpaste.net/~bmc | My opinion only OpenPGP: https://keybase.io/bk2204
