${foo.__} should not expand to parent node

This was an experimental feature that was added after last stable
release. Disable it.

LGTM modulo also removing the now unused nv_parentnode() implementation.

While this was initially experimental, it was subsequently documented in the man page after some bugs were fixed and regression tests were added, which would indicate that it was considered ready for release.

13-08-23  Documented __ in sh.1 man page.
13-08-22 Fixed __ to work in nested types.

So if you still want it disabled, you might want to remove the man page entry and the regression tests. It is an important but minor feature btw for user-defined types and it would be a shame to delay it's release, but whatever.

You are right. I was still going through this code before removing it.
