- There may be other unresolved POSIX.2 demands I did not notice yet.
Please write me if you find one. You can get SUSv2 from The Open
Group <http://www.UNIX-systems.org/> for $0, it contains nearly the
same text for ex/vi as POSIX.2 and is a good reference manual.

- SUSv3 / POSIX.1-200x ex/vi support.
I did not yet decide whether this is worth implementing. It requires
a lot of mostly small changes that make vi more nvi-like in general.
If SUSv3 has as little success in the Open Source world as its
predecessors, it might be better to ignore it and stay on the
officially obsolete SUSv2 / POSIX.2 level.
