(env) in terminal is slow

[jcubic]

If you type this in Dev tools console:

$.terminal.active().echo((await lips.exec('(env)'))[0].toString(), {keepWords: true})

it's fast but for unknow reason it's slow when typing (env) in terminal.

The problem is formatter it try to format that list.

Solution move formatter out of toString, and put in pprint function.
