#11924: r12732 breaks plugin(s) that check(s) if $wp_version is set

 After r12732 (about which see #11881) the PHP Markdown Extra plugin
 stopped working.  I looked at the plugin’s code, and saw that it only does
 its thing (adding/removing filters) after checking if
 {{{isset($wp_version)}}} — which, apparently, returns FALSE after r12732.

 Conversation about the issue from the wp-dev channel:

 {{{
 (2:19:59 PM) demetris: I use a plugin that loads if (isset($wp_version)),
 and it stopped loading after r12732.

 (2:20:42 PM) demetris: I would open a ticket, but I dont know where the
 issue is, or whether it is just sth temporary because of the shuffling
 around.
 (2:21:24 PM) westi|gone: demetris1: I suspect that is because plugins are
 no longer loaded in global scope
 (2:21:43 PM) westi|gone: probably best to put a note on the ticket which
 changed the behaviour
 (2:21:49 PM) dd32: westi|gone: now thats going to have some... MANY
 issues..
 (2:22:18 PM) demetris: Thanks westi|gone.  I'll add a note on the ticket.
 (2:22:21 PM) westi|gone: dd32: probably... can't remember if the
 activation test code runs in global scope though
 (2:22:40 PM) westi|gone: dd32: we may have to undo some of these
 changes...
 (2:22:45 PM) demetris: By the way, the plugin is PHP Markdown Extra (which
 is the one WP plugin I cannot live without).
 (2:22:45 PM) dd32: westi|gone: No it doesnt, Its held inside a function.
 (2:23:08 PM) westi|gone: demetris1: worth putting that info in your
 comment on the trac ticket
 (2:23:28 PM) demetris: westi|gone: OK.  Thanks!
