Given the current release-lines structure, return a default Spec.
Specifics:
* For feature-like issues, only the highest major release is used, so
given a ``manager`` with top level keys of ``[1, 2]``, this would
return ``Spec(">=2")``.
* When ``releases_always_forwardport_features`` is ``True``, that
behavior is nullified, and this function always returns the empty
``Spec`` (which matches any and all versions/lines).
* For bugfix-like issues, we only consider major release families which
have actual releases already.
* Thus the core difference here is that features are 'consumed' by
upcoming major releases, and bugfixes are not.
* When the ``unstable_prehistory`` setting is ``True``, the default
spec starts at the oldest non-zero release line. (Otherwise, issues
posted after prehistory ends would try being added to the 0.x part of
the tree, which makes no sense in unstable-prehistory mode.)
