18 Control arguments:
19 -absolute_pathname, -absp

23 Notes:  Only one name per link is returned; i.e., if a link has more
24 than one name that matches star_name, only the first match found is
25 returned.

27 Since each entryname (or pathname) returned by nonnull_links is
28 enclosed in quotes, the command processor treats each name as a single
29 argument regardless of the presence of special characters in the name.
