Rationale is in the commit description, but it boils down to these tests
being annoying for me recently.  I like to M-x eval-buffer and run tests
interactively, but these tests seemed to work nicely only in batch mode.
In interactive mode they would both fail and issue annoying prompts
"save this modified buffer?" prompts.  In fixing them, I figured out
what they were trying to test and attempted to make that more robust and
clear.
