Theoretically, I'm with you, but if I'm going to be pragmatic, I have to
say that if any one of the -l behaviours are to be the default, it should
be the GNU one, despite it beeing non-POSIX. GNU tar has been in the base
system forever now, and it's become the expected version. We should strive
to be POSIX-compliant, but also try to be true to the history of things.
Also, since it's possible to get undesired effect from using the wrong
option, I say stick to the historical-compliant implementation, -or- give
an error. Don't break compability just for the sake of beeing POSIX-
compliant. It's BSD, not POSIX (og GNU for that matter -- or even SysV)
(A FreeBSD dilletant that's interferring with 'the big guys')
