Instead of writing you own regex to parse escapes, wouldn't it be more sensible to allow someone to enter any of a set of already known escapes such as \xA \c[ \033. Hmm those all are supported by perl and are already interpretated in any qq() or re.
$config{startblock} = qq $config{startblock};
Or something like that (maybe one which actually works).

Update: I was looking for
$config{startblock} = eval "qq($config{startblock})";
Update 2:Nope, that uses eval as tye points out below. Forgot about that when I first posted, thought there was another way using just qq() and not eval, which has all the drawbacks tye mentions.
