 Log Message:
 PR bin/53550
 
 /bin/sh's processing of here doc expansions has changed.   Now it happens
 in the context of the parent shell, so side effects are visible there,
 just like all other redirection expansions.
 
 We need to stop testing that that doesn't happen, and instead test
 that it does.   This is that change.
 
 Add another test case which is testing exactly the example from the PR
 (well, with a different exit status, 1 is too generic and could happen
 by accident) to make sure we don't reintroduce that bug sometime.
