[thinking loudly]

Why not having a (:localtitle ...:) directive which defines the page
title only while the page is directly displayed?

IMHO, after a (quick) look at the code, I would have considered the
following alternative implementation:
* The (:title ...:) directive is only pushing the different title
definitions onto a stack.
* Then, a post processing rule is choosing the top or bottom
definition from the stack according to the current configuration and
set it as the effective page title.
BTW, this kind of implementation would enable writing optional extras
stack manipulation via markup definition.
