    The rationale is that we try to place point such that inserting a char will
    result in a visible new char rather than an invisible one.

That does make sense.  It's a good point that a place where a new
character would be invisible should be avoided.  However, it doesn't
necessarily follow that a place where a new character would be visible
must be ok to put point in.

So my proposal is to treat the neither-side-sticky case as if the end
were sticky, for these purposes.

Do you see any problem with that?
