[rules-dev] DSL expansion: ready for commit

[Wolfgang Laun]

Constraining the scope of applicable when-fragment might be added on top of
the current DSL syntax, providing a compatible migration path. Notice that
constraining the scope is similar to the rule attribute "auto-focus", but
unqualified entries may have to remain active throughout.

Expansion will have to be able to handle insertions not only for the last
preceding pattern but also to other parenthesized condition phrases, e.g.
eval, forall, etc.
