Since 1de44da ("MINOR: ext-check: add an option to preserve environment
variables"), it is now possible to provide an extra argument to
"external-check" directive. This allows to support the "preserve-env"
option which differs from the default behavior.
However a mistake was made, because the config parser doesn't allow the
default configuration anymore: using external-check without argument will
trigger an error:
'external-check' only supports 'preserve-env' as an argument, found ''.
This is due to as small mistake in the code that make the check
systematically report an error if the first argument is not equal to
"preserve-env". The check was modified so that the error is only reported
if the argument is provided, so that the default behavior is restored.
This should fix GH #2380 and should be backported on 2.9 and potentially
further (anywhere 1de44da is, because a note about an optional backport
up to the 2.6 was left in the original commit message)
