echo audit of ltmain.m4sh

[Ralf Wildenhues]

As promised, here is a first cut at an echo audit of ltmain.

I even found one $ECHO "X.." that was missing a corresponding $Xsed
entirely.  This means we are not testing that code path.  :-/

Now while there are many things we do not test..
BTW, is there a way to get at source code coverage in shell scripts?
I had already thought of inserting
  echo $LINENO >>$coverage_fd
every other line of ltmain, just for testing purposes, so that I could
adapt stresstest to the missing bits.  Here documents and multi-line
quotes make this rather tedious handwork, however.  Thoughts?

For you to digest (or not):  HEAD and branch-2-0 patches for echo audit.

Regards,
Ralf
