I don’t think it does.
It displays the path of the .sh script being invoked, but then you have to 
decipher that as well.
Also, when there are failures on workers such as diff-test+param, you can’t 
copy/paste that directly in $PETSC_ARCH/tests/echofailures.sh, you have to 
filter out the diff- and +param part, which is not very practical I think.
