Solaris uses a single '-' to mark the end of the options list:
A - permits the user to mark explicitly the end of any com-
mand line options, allowing rm to recognize file arguments
that begin with a -. As an aid to BSD migration, rm will
accept - as a synonym for -. This migration aid may disap-
pear in a future release. If a - and a - both appear on the
same command line, the second will be interpreted as a file.
