Put page number into <title>

[jidanni]

As mentioned in ​http://perishablepress.com/press/2008/07/21/how-to-generate-perfect-wordpress-title-tags-without-a-plugin/

if ($paged>1){echo '- page ', $paged;}

one finds WordPress (or at least its default theme) should consider
putting the page number of various page 2, 3, 4... into the XHTML
<title> of the page in question, be it search results, archives, or
even the default page of the site. As long as we are on the second or
more of such pages, the <title> should reflect it.

The goal is to make different pages findable in one's browser
history, etc.

(True, Google, MediaWiki, and Trac don't currently do this.)

As you highlight, Google, MediaWiki, and Trac don't currently do this. And it can be done with a plugin.
