    -- Andreas, 2016-07-06 Issue #2047

    -- With parameter refinement, the "parameter" patterns of an extended
    -- lambda can now be different from variable patterns.  If we just drop
    -- them (plus the associated arguments to the extended lambda), we produce
    -- something

    -- i) that violates internal invariants.  In particular, the permutation
    -- dbPatPerm from the patterns to the telescope can no longer be
    -- computed.  (And in fact, dropping from the start of the telescope is
    -- just plainly unsound then.)

    -- ii) prints the wrong thing (old fix for #2047)

    -- What we do now, is more sound, although not entirely satisfying:
    -- When the "parameter" patterns of an external lambdas are not variable
    -- patterns, we fall back to printing the internal function created for the
    -- extended lambda, instead trying to construct the nice syntax.
