Yes it does!  The results may change.  Also the behavior if later
commands in the string fail will be different (roll back earlier
commands vs not).

I disagree.  This is long-established behavior and no one has complained
about it.  We have gone out of our way to preserve it in past changes;
I don't like suddenly deciding that backwards compatibility is
unimportant.  Especially not if only one person is in favor of the change.
