That's the idea.

Right now,

	twill-sh file1 file2 arg1 arg2

tries to run 'file1', 'file2', 'arg1', 'arg2'.  There's no way to
differentiate between that and

	twill-sh file1 arg1 arg2

which would be useful.  So,

	twill-sh file1 -- arg1 arg2

is one way to separate the filenames from the options.

I do want to keep the behavior with 'twill-sh file1 file2 ... fileN' the
same; it's a very handy way to run multiple tests all at one time.
