These lines were last changed to correct a bug:

http://cvsweb.openbsd.org/log/src/bin/ksh/vi.c,v?sort=File#rev1.19

I'm not  sure what that bug  was, but I'm  not sure removing this  is an
improvement.

Also, you don't have to type nonsense to get into vi-mode, you just type
a space and press esc-v. Doing so enters vi-mode with an empty buffer.
