The two lines are checking for the same message, it's just that the
error message is split across multiple lines and thus requires two
greps.  The error messages are actually a bit of a mess, particularly
when they are triggered for multiple paths.  That's something that
subsequent commits will clean up.

I can add a note about this to the commit message.
