I'd like to see this as a recipe. The problem when we edit a page, is that
PmWiki thinks that page is "directly displayed", but renders another source
markup, from Site.EditForm -- and it will accept the (:localtitle...:) as

Unfortunately, the stack will not be the same if the (:title...:) directive is
processed before or after (:inlude...:), and this has to be decided before the
markup is processed. :-)
If a page has 2 (:include...:) markups, the old-way-title stack would look
1. title from GroupHeader
2. title on top - first line of the browsed page
3. title in an included page A
4. title from another included page B
5. title at the bottom - last line of the browsed page
6. title from GroupFooter
Here the last found, in that order, becomes the title.
The new-way-title stack, in the same configuration as before, would be like
1. title on top - first line of the browsed page
2. title at the bottom - last line of the browsed page
3. title from GroupHeader
4. title in an included page A
5. title from another included page B
6. title from GroupFooter
Here the first found, in that order, becomes the title.
