Having used sPatch a little I *might* have an idea. I think I know the
problem you're having and the procedure is rather trial-and-error (one
of the other problems you can get is adding a segment to the line
you're trying to add a point to on the "wrong" side of the existing
point).

However  - there's possibly a sneak way to easily acheive what you
want. Try extruding not once but twice, then delete the middle point
from 3 of the extusion lines. check the OpenGL preview to make sure
sPatch is still filling in the sides (you may well need to draw
crossing lines to complete the shape).

Just an idea.
