Hugo v0.12 doesn't seem to rebuild /index.html when posts are deleted

Hugo v0.12 does not seem to rebuild the home /index.html when a post’s markdown file is deleted. This is on a Mac running OS X 10.10 and Hugo v0.12.

The log below shows that Hugo recognizes updates to post files. When they’re changed, the live reload shows the update on the home page. When a post is deleted, the server log shows it as a “rename” and the home /index.html is not updated. The grep at the end shows that the link to the post is still in that file.
