OK, I can remove this (it was just part of the originals). Shall I resent
the whole series or just a follow-on patch?

The standard logic wants to run each individual test and uses the echo
logic. My tests have their own pass/fail reporting mechanism. As I run
many options on the same tests and have pretty-printing logic, I prefer to
keep that in a run script rather than in a makefile.

I don't care for the echo logic as a mechanism, I think the reporting
should be part of the test. It also doesn't scale past pass/fail - like
xpass and xfail, for example.
