Be smarter about where explicit interwiki links end

Be smarter about where explicit interwiki links end

	* lisp/muse-wiki.el (muse-wiki-update-interwiki-regexp): Make page
	optional, and make interwiki delimiter a regular rather than shy
	group.
	(muse-wiki-handle-implicit-interwiki): Rename from
	muse-wiki-handle-interwiki.  Use match group 3 to get the page.
	(muse-wiki-handle-explicit-interwiki): New function that is
	smarter about where an explicit link ends in a buffer.  This
	allows you to refer to page names with invalid Wiki characters,
	such as underscores and dashes, merely by enclosing them in double
	brackets.
