Agree.
Actually, specifying Gnu tar options without the - is only supported for
compatibility with other/older tar programs. I suspect it will never go
away though as too many people use those utilities using bsd style (no
-) options. See section 3.3.3 of tar info.
There are three styles of options: long (--option), short (-o), and
old/bsd style (o). POSIX does not specify the bsd style and we want to
stay as standards compliant as possible.
