commit: http://git.busybox.net/busybox/commit/?id=a3f71001c30f8927495828da9888bcef86e24035
branch: http://git.busybox.net/busybox/commit/?id=refs/heads/master

"tail -1" works only with one input file. Using it with multiple input
files throws following error on Ubuntu systems:

tail: option used in invalid context

Adding "-n" makes it work on all cases.
