Sorry for the late reply, and thanks for testing the patch.

Just to clarify, I tried applying v2 directly to the REL_19_BETA2 tag
(7873db5369b),
and git apply succeeded without any conflicts, including the change to
src/test/subscription/t/020_messages.pl.

I also checked whether that file differs between REL_19_BETA2 and
master, but found no differences:

$ git diff REL_19_BETA2 master --
src/test/subscription/t/020_messages.pl
$

The same is true for REL_19_STABLE and master:
$ git diff REL_19_STABLE master --
src/test/subscription/t/020_messages.pl
$

So I am not sure what caused the context mismatch.

Separately, I proposed fixing the issue in minor releases, but the v2
patch does not apply cleanly to 14 and 15.
Attached a patch for these versions.
