#328 Refactor: "Extract subroutine" backslashes single quotes

[Dirk Bergstrom]

The "Extract subroutine" refactoring mishandles
single-quoted strings. In the generated subroutine
they are all backslashed.

This:

my @bar = ();
push(@bar, 'boo');

------------

Is turned into this:

my @bar = ();
my () = extracted (\@bar);

sub extracted {
my $bar = shift;

push(
@$bar, \'boo\');
return ();
}

---------------

Note also that the "return ()" statement is unnecessary.
