Description:
{{INCLUDING_PAGE}} for the name of the including page of a template when that
page is included by another page (it is not {{PAGENAME}}).
Motivation: A page (P) may include sub-pages (P1 ... Pn) and the sub-pages could
have their own talk pages. A header template (H) included by P1 ... Pn would
need to refer to [[{{TALKSPACEE}}:{{INCLUDING_PAGE}}|talk]] so a reader of P
could immediately reach the individual talk pages conveniently.
