Adjust in_decl logic to avoid messing up enum declarations.

This is a workaround for an acknowledged upstream bug; it basically
reverts this logic to the way it was in NetBSD indent.  While there
may eventually be a different upstream fix, this will do for our
purposes.  Add a regression test case that illustrates the problem,
and tweak declarations.0.stdout for slightly different formatting
produced for a function pointer typedef.
