practical, clear methods:
Title::getLocalURL() - "/wiki/index.php/Foobar" or "/wiki/index.php?title=Foobar&action=edit"
Title::getFullUrl() - ditto with $wgServer on the front
Title::getInternalUrl() - ditto with $wgInternalServer on the front (for some squid-related functions)
Title::escapeLocalUrl() - local URL escaped for HTML output
Title::escapeFullUrl() - full URL escaped for HTML output
All take an optional query parameter.
Title::getURL(), wfFullUrl() and wfFullUrlE() are now officially
deprecated and will result in instant death. wfLocalUrl() and wfLocalUrlE()
will be killed shortly; they are still used in the language files.
* Converted many instances of globals from the query to $_REQUEST
* Renamed near-useless Title::getURL() to Title::getPartialURL()
* Created new Title::getURL(), to replace wfLocalUrl, wfLocalUrlE, wfFullUrl and wfFullUrlE. Replaced most instances throughout the code
* In Parser.php, generalised stripping of <nowiki>, <pre> and <math> to allow more general use such as nesting
* Moved body of Article::preSaveTransform to Parser.php
* Put lots of comments in Title.php
