bug#19200: Point adjustemnt moves *into* invisible text

No, you have it backwards: position 5 is invisible and position 3 is not.
The "evidence" for that is that if you go to position 3 and insert a char,
that char will be visible, whereas if you go to position 5 and insert
a char, that char will be invisible.

No, this bug is secondary.  The main bug is that we end up at position
5 after C-n.
