Fix another off-by-one error, attempting to output a non-existant field.

rename fgetline() and sharpen axe for bostic...

update for fgetline

fix from Dave Matthews <dave@prlng.co.uk>, with modifications by cgd:
Bug Description:
Two different bugs in join. One causes a segmentation fault if
increasing the space by 100 is not enough. The other gives the
wrong results because the program saves a pointer to the original
buffer rather than to the area where the lines have been copied.

#include <unistd.h>, so getopt(), optarg, opterr, optind, and optopt
declarations can be removed from <stdlib.h>.

Add RCS identifiers.
