Allow multiple string arguments for exec()

See original GitHub issue

I’ve found that I end up doing a lot of messy string concatenation with exec() commands. It would be nice to allow multiple string arguments that would be joined together with a space, such as:

exec('npm', 'run-script', 'test');   // run "npm run-script test"

This could easily be backwards compatible with the current function since only the first argument is currently a string.

@nzakas would this syntax work for you?

exec(['npm', 'run-script', 'test'].join(' '));   // run "npm run-script test"

The concern is that this makes parsing slightly harder, since exec() can take options as well as a callback.

We’re still working on an implementation in shelljs itself, but I implemented a shelljs extension for node v6+ that addresses some of the security concerns here, while also giving a very convenient syntax: https://github.com/nfischer/shelljs-exec-proxy
