[RFE] Disallow spaces in the command parameter

[Fryguy]

This would enforce the usage of the :params when needed, and a user would not be able to bypass it. If they are going to bypass anyway, then there is no point in using AwesomeSpawn.

The only use case we might have to account for is sudo. I say might, because one case easily do

AwesomeSpawn.run!("sudo", :params => ["echo", "hi")

But that is kind of weird. I think I'd prefer another param:

AwesomeSpawn.run!("echo", :params => "hi", :sudo => true)
AwesomeSpawn.run!("echo", :params => "hi", :sudo => "someuser")

Which would be nice because a caller could build the options and call it, then on failure just tack in another option (instead of having to re-call AwesomeSpawn and reorder all of the params.

yeah, I like :sudo as another parameter, because it is not the actual command
