Remove extraneous white space
**What this PR does / why we need it**:
Output from command `kubectl delete --help` contains extraneous whitespace. While we are at it, paragraph in multi-paragraph section has shorter line lengths, text looks better if all paragraphs have similar line lengths.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
**Special notes for your reviewer**:
White space only. This PR is outward facing but so trivial I don't think it needs a release note. I'm new around here, if this assumption is incorrect please tell me. Thanks.

**Release note**:
```release-note
Added flag support to kubectl plugins

add cronjobs to all
Categories were added to the discovery API, but the `kubectl` plumbing didn't make it. We *did* make `kubectl all` gate on discovery information, so it can least be a superset.
`cronjobs` are user resources, so I've added them to the list.
@kubernetes/sig-cli-misc
```release-note
added cronjobs.batch to all, so kubectl get all returns them.

make sure that the template param is the right type before using it
The CLI should attempt to make sure that the flags it uses conform to expectations instead of unconditionally killing a process. This allows for possible re-use of the printing stack.

Protect against nil panic in apply
**What this PR does / why we need it**: `kubectl apply` has a potential panic (actually verified in OpenShift in https://github.com/openshift/origin/issues/15017) where a `patcher` calls the `runDelete` function with a nil `resource.RESTClient`, but under some conditions the client is required by that function.
