[Chris Nandor]

# With Template::Stash
[pudge@yaz pudge]$ perl -MSlash::Test -leDisplay
[% hash = {"" => "foo", "bar" => "baz"}; a=""; b="bar"; hash.$a; hash.$b %]
foobaz

# With Template::Stash::XS
[pudge@yaz pudge]$ perl -MSlash::Test -leDisplay
[% hash = {"" => "foo", "bar" => "baz"}; a=""; b="bar"; hash.$a; hash.$b %]
baz


Yo homzees, Retrieving empty string hash keys is busted up in Stash::XS.
Here is a patch; I can't imagine this early in the morning whether or not
it will break something else (although I don't think that it would ...).
