Hey, yeah, great idea.  And why not use '---' to force switching to
Linux compatible mode, and '----' to switch to BSD syntax, and '-----'
for System V syntax (5 hyphens, System 5, easy to remember).  Oh, and we
might need a way to switch back to Plan 9 syntax.  That better be ''
(0 hyphens).

Example:

  cat ---- -s ----- -s '' -v

prints the contents of file named '-v', squeezing multiple empty lines
(BSD -s) and silencing error message (System V -s).
