+ * lib/idcache.c (getuser): Return NULL (rather than stringified uid)
+ upon lookup failure.
+ (getgroup): Likewise.
+ (getuidbyname) [NOT_USED]: #ifdef-out unused function.
+ (getgidbyname) [NOT_USED]: #ifdef-out unused function.
+ Suggested by François Pinard.
+ * src/ls.c (print_long_format): Reflect changes in semantics of
+ getuser, getgroup.
