Thanks.

I now noticed linespec.c:decode_dollar also does
the same thing, another candidate for refactoring/reuse.

What does the _ref mean in value_from_history_ref?

This is not a badly formed history value.  It's a user
convenience variable.  I'd make the test check that
such convenience variables work as intended.

Otherwise looked fine.  Thanks again.
