Sander van Harmelen ef9054562e commands: make sure the correct flagset is used
A lot of commands used `c.Meta.flagSet()` to create the initial flagset for the command, while quite a few of them didn’t actually use or support the flags that are then added.

So I updated a few commands to use `flag.NewFlagSet()` instead to only add the flags that are actually needed/supported.

Additionally this prevents a few commands from using locking while they actually don’t need locking (as locking is enabled as a default in `c.Meta.flagSet()`.
