highlighter: underline valid "cd" arguments also if they come from CDPATH

Browse Source 
When visiting the "cd" node, we mark invalid paths as error, but don't
underline valid paths.  This works fine most of the time because we later
underline paths (for any command, not just "cd").
However the latter check fails to honor CDPATH.  Let's correct that, which
also allows to simplify the logic.
