 === Scenario ===
 Title-less blog posts are common in linklogs (aka asides). Currently
 !WordPress does not generate titles for these types of posts, which has
 two implications:
  * nonexistent titles appear in feeds, which break some aggregators that
 rely on the existence of a title to link back to the post
  * post_names (aka slugs) get generated based on the post ID, creating
 human-unreadable permalinks, e.g. {{{http://example.org/2007/02/4201/}}}

 === Prior Art ===
  * Blogger uses the first 32ish characters of the post for the post_title
 and post_name, without breaking a word in half
  * [http://kottke.org/ Jason Kottke] generates a post_title based on the
 first 70ish characters of his post, without breaking words, adding
 ellipsis to titles that were based on truncated content. Note: the
 generated title is only visible in [http://feeds.kottke.org/main his
 feed].
  * I'm not sure what MT does

 === Proposal ===
 I propose that !WordPress generate a title for title-less posts, at the
 moment the post is published (similar to how a post_name is generated)
 based on the first 100 characters of the post_content (excepting html
 tags).

 This generated title would then be the basis for the post_name. In the
 event that 100 characters falls in the middle of a word, that word would
 not be included in the generated title. For all titles generated from
 content greater than 100 characters in length, 3 periods ({{{...}}}) will
 be added to the end of the title (aka an ellipsis) which wptexturize will
 later translate into a ellipsis entity.

 === Implementation ===
 I've implemented this as a function called
 {{{generate_title_from_content()}}}, see attached patch.
