	* etags.el (tag-lines-already-matched): Remove defvar.
	(initialize-new-tags-table): Don't make that var local.
	(tag-lines-already-matched): Add docless defvar near find-tag-in-order
 	defun; this is a global state variable for that one function.
	(find-tag-in-order): Move clearing of tag-lines-already-matched out of
 	loop.  Make it a list of markers and search it with member; it is now
 	global, not buffer-local in the tags table, and records all matches in
 	any tags table during a single find-tag loop.  When we run out of
 	matches, clear it and null out the markers.
