The CodingGuidelines said we want to spell `$nr` instead of `nr`
inside arithmetic expansion for dash older than 0.5.4

I'm not sure if we should go with just `$((nr+1))` or it's better to
loosen our Guidelines. Since Debian Jessie (oldest supported Debian)
ships 0.5.7. I don't know about other systems.
