I have updated the documentation/README to provide background and rationale, and elaborated a bit on other comments. OpenBSD's vi (and OpenVi) differ distinctly from both Nvi (https://repo.or.cz/nvi.git https://repo.or.cz/nvi.git) and Nvi2 (https://github.com/lichray/nvi2 https://github.com/lichray/nvi2) in terms of features and support, having diverged 25 years previously, where the OpenBSD/OpenVi branch has embraced minimalism and simplicity. For a quick and non-scientific comparison, C source lines of code (as counted by tokei) for the various distributions of the Nvi-derived editors: Nvi - 62,315 SLOC Nvi2 - 32,408 SLOC OpenVi - 40,065 SLOC And looking ONLY at the core editor functionality and bundled regular expression engines: Nvi - 35,874 SLOC Nvi2 - 32,019 SLOC OpenVi - 31,678 SLOC
