Somehow, this deletion makes this patch fail to apply. As in, the
rejected hunk is literally the following:

---

diff a/src/test/run_test_zones.pl b/src/test/run_test_zones.pl	(rejected hunks)
@@ -29,7 +33,6 @@ sub read_sdn_config {
     return $sdn_config;
 }
 
-
 my @tests = grep { -d } glob './zones/*/*';
 
 foreach my $test (@tests) {

---

... I don't know what happened here, but this can still just be applied
otherwise - in my case, I resolved this via the following:

* `git am --reject`
* `git add src/test/run_test_zones.pl`
* `git am --continue`

Then it just applies. When in doubt, one may also check
`src/test/run_test_zones.pl.rej` to see what was rejected - should be
just the hunk I pasted above.

IMHO this can also just be done when applying the series; while
*somewhat* inconvenient, I don't really see this as a blocker or
anything.

So, LGTM!
