I have played with extensions of your patch that fix the testcases here
as well as the fallout from regression testing.  To be attached later.

This patch fixes the testcases in this PR and regtests OK, except for the
necessary minor adjustments to the patterns in gfortran.dg/data_char_4.f90
and gfortran.dg/data_char_5.f90 (not included).
