thanks for the examples
you can use the ast sed (with option -A for the negation tests)
to compare ksh93 vs sed substitution
both use the same underlying ast <regex.h> implementation
the intention is to maintain compatibility between the two where possible
I have a test set up and will get back with details
after the reason for the differences can be located
and either rationalized or fixed
