Yeah, the fact that it's a possible feature is why I termed it
a "buglet" as opposed to a "bug".  I'm still trying to work out
the correct handling for (:title:) in the face of includes.

Currently I see several possibilities:

  - Leave things as they are now (arguably broken), where the 
    last (:title:) statement encountered is the one that counts.

  - Change (:title:) so that the first (:title:) directive
    encountered is the one that counts -- even if the first
    (:title:) comes from an (:include:) statement. 

  - Use the "outermost" (:title:), i.e., a page's (:title:)
    directive takes precedence over any (:title:) directives
    in an included page.  However, a page without a (:title:)
    will use an included page's (:title:) if there is one.

  - Never honor (:title:) in any included pages.

I see arguments for and against each of the above -- it's not
obvious how it should work.

And if we do decide to change it, there will be a 
$Transition['title']=1; setting that restores the current 
behavior for those who need it.
