KeyFile.getComment

Retrieves a comment above key from group_name. If key is null then comment will be read from above group_name. If both key and group_name are null, then comment will be read from above the first group in the file.

Note that the returned string does not include the '#' comment markers, but does include any whitespace after them (on each line). It includes the line breaks between lines, but does not include the final line break.
