The good thing is that this isnt a general case. He isn't trying to extract a quoted string from a stream afaict, but rather from a variable that he probably has considerable control over. In that case I would imagine that something like 

my $arg=shift;
$arg=~s/\A(["'])(.*)\1\z/$2/s;
$arg=quote($arg);

would be perfectly acceptable, and if he had total control over the input then a simple $arg=quote($arg) unless ($arg=~/\A(["']).*\1\z/s) would suffice, and might even offer interesting power play opportunities.
