A third condition is that the text in the put buffer contains spaces.  What
seems to happen is that a space on which wrap should occur AND the character
following it are not inserted.  Instead, the non-space characters following
each such space are interpreted as commands(!), in the reverse order of that
in which they occur.

This annoying bug has been in vi as long as I can remember and has persisted
up through BSD 4.3.  It has been signalled before on the net.  It is
probably just a silly coding error that should be easy to spot (assuming
you know your way around in the vi code), what with such specific and
repeatable behaviour.
