+ Moved all internal definitions from usermgmt.h to user.c + Added prototypes to usermgmt.h + Allow defaults to be set at build time + Check the effective uid is 0 if any data is to be modified + Check all numeric uids and gids really are numeric + Fix a bug (reported by lenb at sasquatch.com) where new ranges were appended to old ranges, rather than replacing them + Add userinfo(8) and groupinfo(8) utilities (if EXTENSIONS is defined), whereby user and group information can be displayed. Add manual pages for new utilities. Add front-end calling from user(8) and group(8) accordingly. + Make all functions visible outside the user.c file again. User and group manipulation may be split out into a separate shared lib in the future + Split off main function into a separate main.c + Changed default group to be "users" + Changed despatch table for commands to work in a more sane manner + Added "default-group" target to Makefile, so that the default group can be made easily.
