I submitted a patch to current around 2005 to get libedit upgraded to the latest NetBSD version. The version in the FreeBSD 4.x tree was an ancient version that was incompatible with most programs that attempted to use it (ie.. ssh). Stefan Farfeleder was kind enough to port those patches into something usable in the base system. The 6.x tree contains those updates. This porting from NetBSD happens periodically as bugs and or an itch needing to be scratched happens to prompt it. As to why the readline compatibility shims are removed from the base libedit.. well I suspect that it's that way to prevent the readline in base and or ports from being ignored and misconfigured, AND those programs that can use libedit's native API are configured to use it and not readline. -Phil.
