• [x] Is this PR targeting the correct branch in this repository?

Steps to test this PR:

1. View a post that has a wpcf-shirttail custom meta field, such as http://sfpublicpress.flywheelsites.com/remaking-rent-control-if-voters-approve/ (post ID 3443) and make sure it displays at the end of the post content
2. View a post that doesn't have that custom meta field and make sure nothing funky is happening

post 31858 without custom meta looks good.

Do we want this to wrap the field output in a lightly-styled div.entry-content.wpcf-shirttail or something to help differentiate this HTML from the post content preceding it?

Current styling in the Drupal site:

Will the italics carry through automatically? What would it take to add a simple line divider? Other suggestions? Simpler the better.

[joshdarby]

@MirandaEcho The italics should carry over as long as they're part of the HTML in the field. It would take ~5 minutes to add a divider line.
