{{content words}} error with CTA

[cathysarisky]

Issue Summary

Using {{content words="10"}} should probably return 10 words whenever possible. Things get messy if there's no access to the post. [Aside: it's also possible to pass 'characters' and that has exactly the same problems.]

Background: Some themes use the {{content}} helper with words to generate a short preview, for example for an index page.

Steps to Reproduce

Here's the behavior that can occur when the helper is used with words=10 . In my post.hbs, I've added
{{content words="10"}}

Create a post in the editor. Make it 20 words. long.
Expected: See the first 10 words. Actual: First 10 words.

Set post access to members only (don't be a member).
Expected: ? Not sure, honestly? Actual: Entire CTA. This generally breaks the layout, although the theme can avoid it by checking for access before using {{content}}.

Add a public preview line after 20 words. Add some more words after it.
Expected: 10 words. Actual: All 20 words, PLUS the CTA. I can use {{{html}} instead, but it doesn't take a words argument.

Proposal & ideas

If the public preview is longer than the words value, return only the words, no CTA. [We certainly shouldn't return more words than requested.]
If the public preview is longer than the words, truncate it at the listed words, followed by the CTA.
If there is no public preview, then... ?

Would it make sense to add a "noCTA" option that causes {{content}} to write out the smaller of "words" or the public preview if words is set, or the public preview (minus CTA) if words is set, or nothing if there's no preview?
