<https://unix.stackexchange.com/users/22565/st%c3%a9phane-chazelas> over
at StackExchange offers this:
cc=( "${cc[@]/#%^*$~zsh_case${filter}*}" )
... and it seems to do exactly what I want. I understand the negation
and the way the '[@]' and the outer quotes protect the length of the
array, now I just need to understand the '#%' anchors -- but they are
essential.
