Oh! I just noticed this while testing changes to use XFAIL, there is an
alignment issue: one too many spaces after "XFAIL" above, which leads
to misaligned output.

		fprintf(TH_LOG_STREAM, "#      XFAIL      %s\n", \
                fprintf(TH_LOG_STREAM, "#      SKIP      %s\n", \

Compare the position of "%s" above...
