I think an environment variable would be better than a command-line
option.  During development/testing, I'll want to enable POSIX-only
mode, to ensure that I don't use any non-POSIX features.  But if this
is done by a command-line argument, then when I'm done testing, I'll
have to change my sed invocations to remove that argument before
releasing my code, since not all sed programs will support the
argument.  With an environment variable, my code doesn't need to be
changed.
