Every other tar implementation I've looked at supports either both
dash-less argument, and arguments with dashes, or only dash-less
argument. sbase tar is the only tar that only supports arguments with a
dash, so to use tar as portably as possible, one has to not have a dash
with the argument, and sbase tar should be made to accept that style of
argument to fit with the more portable usage.
