Subject: Check lrls wrapper for a couple edge-cases

Changes:

- Remove `-A` so end-users can optionally pass that in.
- Avoid depth checking when it can produce ambiguous output.
- Avoid path stripping when it can produce ambiguous output.
- Only columnate when output is to a terminal.

Closes: #25 [via git-merge-pr]
