Shouldn't $(echo $quoted_name | tr -d '"') be the (double-quoted) expression "${quoted_name//"/}" instead ?

@Anvil indeed, thanks, changed + pushed.

I would love to see this get merged in. I currently put something almost exactly like this in my 'setup' routine and use it to call 'skip'.

Any chance this got merged? It's super useful for me too.
