Michael Forney d2824f5294 Revert "Do not use arg.h for tools which take no flags"
This reverts commit 9016d288f1.

Tools that have no options are required by POSIX to support "--" so
that conforming applications have a way to shield their operands from
implementations that provide options as an extension.

echo(1) is just an exception, so it is handled specially.
