(#<widget> 'tag 'prevrange tagName index1 ?index2?): This command searches the text for a range of characters tagged with tagName where the first character of the range is before the character at index1 and no earlier than the character at index2 (a range starting at index2 will be considered). If several matching ranges exist, the one closest to index1 is chosen. The command's return value is a list containing two elements, which are the index of the first character of the range and the index of the character just after the last one in the range. If no matching range is found then the return value is an empty string. If index2 is not given then it defaults to the beginning of the text.
