Here is another, as I seem to have managed to kill another one ;-)

"VAR=VAL command" is sufficient to run 'command' with environment
variable VAR set to value VAL without affecting the environment of
the shell itself, but we cannot do the same with a shell function
(most notably, "test_must_fail"); we have subshell invocations with
multiple lines like this:

	... &&
	(
        	VAR=VAL &&
                export VAR &&
                test_must_fail git command
	) &&
        ...

but that could be expressed as

	... &&
        test_must_fail env VAR=VAL git comand &&
	...

Find and shorten such constructs in existing test scripts.
