* When we discover the comment comes from a transcluded page, follow
the transclusion to find the source page. We follow transclusions
recursively, up to an arbitrary limit of 10.
* In the reply widget, display the title of the page where we will
save the reply, to avoid users confused why their edit won't show up
in the history. In the wikitext workflow this is done by redirecting
the user to the edited page at the end, but it seems less surprising
to stay on the current page.
* After saving the reply, we must purge the current page, otherwise
the new content will not be immediately visible on it.
