[PATCH] defaultenv: don't overwrite in config

[Uwe Kleine-König]

This patch prooved to be useful while working with a colleague on a single
machine. It allows to switch the user without editing /env/config by
just issuing:

	export user=me

. Note, in bash this construct (i.e. an if without body) bails out with:

	Syntax error: "fi" unexpected

but in hush it seems to do the right thing.
