I am somewhat lukewarm on this part of the change.
The added "regardless of..." does not seem to add as much value as
the two extra lines the patch spends. If we say something like:
A `struct dir_struct` structure is used to pass options to
traverse directories recursively, and to record all the
paths discovered by the traversal.
it might be much more direct and informative, I suspect, though.
After all, the word "traversal" pretty much implies that the library
goes in and out of the directories recursively.

Good eyes.

The "one" does not refer to a "directory", but to an "exclude-list".
Pop the ones that are not for parent directories of the path
being checked
perhaps?
