Slowly I figure out what's really going on and don't have to rely on 
rote copying of syntax.

Heavy duty diagnostic stuff it seems.

Ah!  When you type it in there verbatim it seems to always be the 
pattern, but as a variable who's to say that the intention is?  So some 
way of making it explicit avoids semantic confusion.  That's robust, I 
like it.  One more little thing:


string="${cc[$aa]/*(#i)$filter*/}"
if [[ "$string" ]]; then
cc[aa]=''
else
cc[$aa]=${cc[$aa]/(#b)($~zsh_case${filter})/$'\e['$color;1m${match[1]}$'\e[0m'}

... to delete non-matching lines, but I'll bet there's a better way than 
this failed substitution.
