Fabulous:

         for filter in "$@"; do

             cc=( ${(M)cc:#*$~zsh_case${filter}*} )

             cc=( 
${cc//(#b)($~zsh_case${filter})/$'\e['$color;1m${match[1]}$'\e[0m'} )

         done

... no need for a a loop processing each line one at a time. Once the 
non-matching lines are removed, the whole array can be colorized in one 
gulp.  I knew there'd be an elegant way.

IF you know what you are looking for! I can't look for '(M)' before I 
know the thing exists to be looked for.

This mortal would need to devote a year to it.  I have tried but one 
needs to understand the jargon before it's even intelligible. But yes, 
it needs to be learned from the outside in.  You experts don't realize 
how steep the learning curve is.  Oh, for a glossary!
