svn commit: r281129 - head/etc

Seems like a couple things need to be done:
1. The change might (imply optional) need to be reverted to avoid
violating POLA.
2. All of the applications with Unicode issues need bugs filed for
them and need to be fixed. Documentation should be added in the
Handbook or somewhere else to advise users of Unicode issues with
applications.
3. If UTF-8 was turned off in 1., it should be turned back on once
enough enough is fixed that basic functionality talks UTF-8 well.

If nvi is a stopgap, providing an alternative might be "good enough"
for folks to use UTF-8 profiles (vim for instance).
