One way to move thru the history of recent pairs is to put all pairs to
the default list of M-%.  Every pair needs to be in the same format as
currently used to display the default value in its prompt - with an arrow
separating the FROM and TO arguments like "from1 -> to1".  This has a drawback
that after typing RET with a string in this format, query-replace needs
to parse it, and separately add FROM and TO to the history lists.
