There is a backward-compatibility problem with supporting "tail -2" with
any number of extra arguments, since (for example) "tail -2c 20" has a
different meaning in traditional "tail" than you might think. To avoid
confusion, "tail -2" is not encouraged when using non-traditional
features (in your case, two or more FILE arguments). Since "tail -n2
FILE1 FILE2 ..." suffices, it's not clear that it'd be worth the
aggravation to rethink this.
Given the above, and no further comments,
I'm closing this bug.
