[Presentation-layer-only] Use a default environment name about hsenv HOT 4 CLOSED

I've thought about this previously, but haven't done anything about it yet because I wasn't sure of the best approach.

For one thing, since d4e92c5, you can pass --no-ps1-indicator to your initial hsenv command to omit the prompt indicator altogether. What if we just do this automatically if no name is specified, i.e. only show the indicator if there is an actual name to be shown?

I'm also not opposed to some kind of default indicator that shows up if you haven't set a name for your sandbox, but I don't like defaulting to (hsenv) because there's no way to distinguish that from an actual sandbox called hsenv. That's probably a silly thing to worry about, but I think it would be better to disambiguate it somehow, say, by using square brackets instead of parentheses or something like that.

Any thoughts on these options?

Uhm, I have to be honest, I love my indicator, it's the only visual aid that helps me not doing something stupid like 'cabal install myPackageWhichWillBringMeToCabalHell' :D
It's too easy to forget if you are or not in a sandbox environment, so definitely +1 for keeping the visual indicator!
I agree that someone could create a sandbox with the name "hsenv":
Why why don't use simply a randomly generated number using say, for example randomR?
This way we still keep our visual indicator, making it a bit more prominent, still avoiding clashing :)

I went with the [hsenv] indicator, using square brackets to indicate a nameless sandbox. Does that work for you?

Sure! Thanks! :)
