The FROM value is stored in history even if you abort the query and
replace without completing it:

emacs -Q
M-% foo RET
C-g
M-% M-p (this should recover "foo").

There's room for improvement, though.  If there are complete query
replace items of the form FROM -> TO, then they are placed before the
FROM entries in the history.  Perhaps there should be a mechanism to
recover those FROM entries from history more quickly.
