Package branch specification in openbsd_pkg module vs. package module

[Darren S.]

Greetings,

Attempting to understand why this difference exists installing a
package on OpenBSD 6.0 using the more general 'package' module vs. the
underlying installer module 'openbsd_pkg'. The package is given in
format supported for recent version of OpenBSD's package tools where
the branch can be specified using a '%' as the delimiter after package
name, hence below I use 'php%5.6' to install the PHP 5.6 branch from
package repo.

OS: OpenBSD 6.0 amd64
Python: 2.7.12 cpython
Ansible: 2.2.0.0


Value of variable used in tasks:

php_ver: "5.6"

Failure case task:

- name: install php
package:
name: "{{ item }}"
state: present
with_items:
- "php%{{ php_ver }}"
tags: [httpd, web_stack, php]

Result:

I understand from documentation on the 'package' module that it calls
the underlying OS package module anyway (can see openbsd_pkg.py in
output above) so curious why this fails when using the 'package'
module in the task?
