Relieve checkin_update and checkin_init of the responsibility of

calling rcs_close() so we don't try to rcs_close() the same file
twice if the working file does not exist, resulting in a core dump.

The current code also returns the status of the last file, so if
we do:

	$ touch file
	$ ci nonexistent file

that will return 0.  GNU returns 1.  Fix that.

Additionally, it returns -1 on error, which turns into 255.  It
should return 1.
