This still depends on that the output has Cc: before Subject: and
there is no other header that can have an address on it.  E.g.

        To: a...@example.com
        Cc: b...@example.com
        X-foo: <<whatever address you are looking for>>
        Subject: [PATCH] A sample patch

would still say that the address is _on_ the CC: list.

I do not usually do awk, but I think you should be able to avoid
capturing output from it, echoing and then grepping, which is way
too ugly.  Perhaps you can start from something like below?

#!/bin/sh
awk '
        BEGIN { in_cc = 0 }
        /^[Cc][Cc]: / {
                sub("^[Cc][Cc]: *", "")
                in_cc = 1
        }
        /^[^    ]*:/ {
                in_cc = 0
        }
        /^$/ { exit }
        in_cc {
                sub("^ *", "")
                sub(", *$", "")
                print
        }
' <<\EOF
To: a...@example.com
Cc: b...@example.com,
