yes, ithat was my mistake, sorry.

I agree.  When I thoought about the test, I wasn't able to invent somethig
usable.  As you pointed out, my test
        /^[ \t]*case/,/^[ \t]*esac/{if(/\[\^.*\)/) exit(1)}
will probably have many false positives.

The previous test,
        grep '\@<:@\^.*).*;;'
was very weak; it needed the pattern and ;; on the same line.  Yet it
also had a false positive; that was what brought my attention here.
(Yes, the workaround is to put ;; on a separate line, but this is ugly.)

So I conclude there is no good solution now and it's best to let it be.
Thank you, Paul, for fixing it.

(If we had a shell which is able to complain when it sees [^..], that
would be the real fix!)

Have a nice day,
