This bug is also in the oldest version of vim I have already
compiled, 7.2.330.
If I understand the original author's intent, then the following
patch to 9.0.2185 seems to fix it. I may have missed something, but
I ran "make test" before and after the fix and the same tests failed
both times, so this fix doesn't break anything being tested.
