Hi, I'd say that's debatable. From
http://www.opengroup.org/onlinepubs/009695399/utilities/dot.html
EXIT STATUS
Returns the value of the last command executed, or a zero exit
status if no command is executed.
This leaves no room for a failure exit code on wrong usage, although the
file argument is not optional in SYNOPSIS. It either is wrong usage,
but no failure exit code defined, or it's "no command is executed", and
exit code is 0.
I'd prefer not to change dash.
Regards, Gerrit.
