That would mean that after doing a C-g, the next time you do M-% the
suggested replacement the will be "LAST_FROM -> ", i.e., replacing the
last from-string entered with the empty string, instead of the last
"good" pair of values as the bug reporter wanted.  Maybe this is
acceptable behavior, I don't know.
