When one of settings.originalContent && settings.changedContent are empty

[paolof76]

When one of the two values are empty, the diff is not shown in case of originalContent and changedContent are passed as parameters.

Example (pass an empty originalContent):

$("input[type=button2]").click(function () {
$("#wrapper tr").prettyTextDiff({
cleanup: $("#cleanup").is(":checked"),
originalContent: "",
changedContent: "Some more text which can be passed to this function.",
diffContainer: ".diff2"
});
});

A quick fix I found to let it work is to split the if (settings.originalContent && settings.changedContent) {} in two separate checks:
if (settings.originalContent) {
original = $('

').html(settings.originalContent).text();
} else {
original = $(settings.originalContainer, this).text();
}
if (settings.changedContent) {
changed = $('

').html(settings.changedContent).text();
} else {
changed = $(settings.changedContainer, this).text();
}
