Brian Goff 8bdbf874a2 Refactor attaches copyEscapable ...

`copyEscapable` is a copy/paste of io.Copy with some added handling for
checking for the attach escape sequence.

This removes the copy/paste and uses `io.Copy` directly. To be able to
do this, it now implements an `io.Reader` which proxies to the main
reader but looks for the escape sequence.
