You have a few.  Here's one, from "Action Arguments" in the Emacs
manual:

     *Warning:* If previous command-line arguments have visited files,
     the current directory is the directory of the last file visited.

Info was designed to display on the dumbest text terminals out there.

I hope others will chime in.

This is documented in the Texinfo manual.
