File with patches to change lowercase links to uppercase links
Please change "MediaWiki:message" links to "MediaWiki:Message" links in the files I gave in the patch.
In normal, case-insensitive wikis, such lowercase letters in links to messages cause no problems.
But if you follow such a "MediaWiki:message" link in a case-sensitive wiki (like Wiktionary), and then edit that message, and you will see nothing has changed. If you then edit "MediaWiki:Message", you will see your changes are working.
This was also the reason for revision r27860.
