I'm surprised this test passes as-is, as it doesn't look like you added the
twitter URL to the list of pages the URL has visited.  (See TestURLInfo above.) 
Did you actually run this test?  (build components_unittests, run it with
--gtest_filter=HistoryQuick*.*)

Also, in addition to making sure this test passes, please double-check that this
new test fails without your change.  (One easy way to check is to make a copy of
the .h and .cc you've changed, remove those changes, build and run the test to
see if it passes or fails, and then replace the .h and .cc with your copied
files to restore your changes.)

Can't I just start up the latest release instance of Chrome (on any machine),
enter the twitter URL and go through my test sequence of "funtimes" then
"fungoodtimes"?  When I do this it fails.  When I run an instance of Chrome with
my new code it works....Done.

This function declaration and the one below shouldn't be here.  Did you
accidentally copy-and-paste them here?

Deleted those lines....Done.
