No, I mean turning this rather baroque expression that creates the array
"target" (and that I can't follow as it stands without detailed
investigation):

${${(f)"$(_call_program targets $words[1] -sT $opt_args[(I)(-N|--nosearch)] ${(kv)opt_args[(I)(-f|--rakefile)]} 2>/dev/null)"}/(#b)rake ([^ ]##) ##\# (*)/${${match[1]}//:/\\:}:${match[2]:l}}

into a function that assembles the completion.  That might at least make
it obvious what's going on.

However, it might be worth seeing if replacing _describe as the function
to add the completions (just below that expression) helps.  _describe
treats colons specially, and although the colons are being quoted with
backslashes in the expression above, I wouldn't be 100% sure this
actually has the right effect.
