plugin_action_links filter does not include page & search context

[wpmuguru]

The default links in the plugin list tables return the user to the same context (search, page, etc.) that they clicked a link on. A plugin adding links via either of the plugin_action_links filter doesn't have access to either the page or search context.

Patch is attached.

FYI, both variables are globals here.

I think that we will find a lot of places where this is true or where actions/filters are missing.

Not sure this is 3.1 material

[wpmuguru]

I'll punt since the variables are global.

As noted above, the two contextual variables in question are global already.
