We now use a new variable, "wrap", to track if a wrap should be
done, which is true either if "auto_wrap" is true or if the user
chooses to wrap in the dialog.
This preserves the meaning of the "auto_wrap" variable and also
removes the confusion of why the previous code of
if (!auto_wrap) {
...
}
if (auto_wrap) {
did not use an "else" instead of the second "if".
No change in functionality.
