Yes, the curls are Smarty...if you don't understand Smarty, it is difficult to edit X-Cart templates, as they are all based on that language. You want to look for the bit of code that looks like this:
{if $discount gt 0}{if $config.General.alter_currency_symbol ne ""},{/if} {$lng.lbl_save_price} {$discount}%{/if}
Add more spacing before the {$discount}% part using for a space.
