Without this fix, generating documentation results in:
```

- Make sure exit_json() always returns a changed= value
- Modify the yum module to not return failed=False
- Modify install() and latest() similar to remove() in yum module
- Changed exit_json(failed=True, **res) into a fail_json(**res)
- Make sure yum rc= value reflects loop (similar to how we fixed remove())
Rewrote switch_version() to read .git/HEAD to find branch associated
with HEAD. If in a detached HEAD state, will read
.git/refs/remotes/<remote>/HEAD.
Rename pull() to fetch(). It does a git fetch and then a
git fetch --tags.
Add _run() method to handle all subprocess.Popen calls. Change
all previous calls to subprocess.Popen to use _run().
There is no need to require thirsty mode when the destination is a directory. We add the basename of the url to the destination directory and proceed with that. If that file exists in non-thirsty mode continue as expected.
I also cleaned up some of the logic that is no longer necessary if we simply rewrite the destination from the very start the way it is expected.
I had made and pushed this change after you already pulled the request.
@dhozac indicated that it would probably be better to use return codes > 255 for anything related to Ansible itself. Which makes sens :)
We use the lineinfile module to modify configuration files of a proprietary application. This application reads configuration options from files, but does not require those files to exist (if the default options are fine). However this application may modify the configuration file at will, so we cannot copy or template those files. And after a silent install the configuration may not exist (depending on the response file).
Whatever the case, during deployment we need to make sure some configuration options are set after the installation.
So the cleanest way to handle this situation is to allow the lineinfile module to create the file if it is missing (and this is the expected behavior). When I proposed this behavior, @sergevanginderachter needed the same functionality and was now working around it as well.
