Sorry, my bad. If you need a suggestion, here you are: re-read our
contribution guidelines, especially the following bullet:

Do you need the location of definition (:123) or location where the
function execution is stopped at the moment (:142)? If I got your point,
you prefer the latter, right?

It may not, considering the flags used for obtaining debug info.

Yes, <currentline> field is provided by 'l' flag[1]. Please, get rid of
<linedefined> and the default 0 and drop a few sentences regarding this
change in commit message.
