Format the subshells introduced by the previous patch (Several tests:
cd inside subshell instead of around, 2010-09-06) like so:

	(
		cd subdir &&
		...
	) &&

This is generally easier to read and has the nice side-effect that
this patch will show what commands are used in the subshell, making
it easier to check for lost environment variables and similar
behavior changes.
