http://mxr.mozilla.org/mozilla-central/source/browser/base/content/test/browser_tabMatchesInAwesomebar.js In order to port this test, the file needs to be copied to the same directory (perhaps with "_perwindowpb" appended to its file name), and then instead of setting privateBrowsingEnabled, we need to open a new private browsing window and then run the test on that window. Note that the original test should only be added to the list of test files in Makefile.in ifndef MOZ_PER_WINDOW_PRIVATE_BROWSING, and the new test file should be added to the list with the reverse condition.

This basically removes the PB checks from that test, since we test all interesting combinations in browser_bug816527.js. Taking this in order to help make Birch green again...
