bin/: Use explicit "--" separator for assert-arg usages
In order to prevent legitimate cases to fail as errors, such as:
NUM='-10'
eval "$(assert-arg "$NUM" '-n NUM')"
To prevent assert-arg(1) from treating "-10" as the options "-1 and -0,
they need to be put after the "--" separator.
This way, all usages of assert-arg(1) that had its first argument as a
variable were adapted, and the usage and examples of assert-arg itself
were updated to encourage this best practice.
