Currently when you access a MediaWiki message in a default install, the initial tab will read "create" because the page itself doesn't exist (it has no row in the page table). However, if you click "create", it will pre-fill the textarea with the default message and will appear, for all intents and purposes, to already exist.
If a valid MediaWiki message is accessed (that is, a MediaWiki message that corresponds to an entry in a messages file), the tab should read "edit". This is more intuitive. If the message isn't registered (e.g., MediaWiki:ffdjsifojsdf), the tab should read "create".
This caused confusion to a user in MediaWiki-General.
