* $stack is not modified in Profiler::calltreeCount(), no need to pass-by-ref.
* Add FIXME marker to non-cross-platform line.
* A freshly created string does not need to be returned by reference. [Xml::namespaceSelector() and HTMLnamespaceselector() ].
* Use RFC 2822-style date/time format instead of localized formatting for
the expiry time in the protection form; while ugly, it actually works;
a localized time is usually lossy (changing the time on submit) and
more significantly will fail for any UI language that's not english!
* Rearrange some of the form display logic to handle error conditions
a little more gracefully; invalid expiry format caused the form to
be displayed twice.
* Should be nicer on session token expiration as well, showing the
form instead of just an exception message.
* removing some unused global declarations.
* removing or commenting out or adding comments for unused local vars.
* Adding one or two local var declarations.
* Declaring $matches array passed to preg_match() / preg_match_all() as array() before using [not required, just have a slight preference for the explicitness].
* remove one or two pass-by-reference function declarations where the value is not modified.
* Adding some braces to if-else blocks.
* In Parser.php, stripstrate is now an object rather than an array as per r17820, so we no longer need ask for a reference to it (as in "$x =& $this->mStripState;"), and in fact it's probably just simpler to get rid of $x altogether.
* Moving some preg regexes from "" quoting to '' quoting to stop static analyzer whinging about bad escape sequences.
... up to "LinksUpdate.php" in the includes/ directory.
* Deleted DatabaseMysql.php, no longer necessary, database classes are autoloaded.
* Moved wfGetMimeMagic() to MimeMagic::singleton()
* Fixed a couple of __CLASS__.'::'.__FUNCTION__ things.
* (bug 675) Add page protection level for unregistered/new accounts
* User::isNewbie now uses the registration date and $wgAutoconfirmAge
* Log views show message when no matches
