The "?" help for query-replace mentions many things,

Type Space or `y' to replace one match, Delete or `n' to skip to next,
RET or `q' to exit, Period to replace one match and exit,
Comma to replace but not move point immediately,
C-r to enter recursive edit (C-M-c to get out again),...

But it doesn't mention how to even one little undo.

One little undo [C-/] is all it takes to break a, say,
dired-do-query-replace-regexp or other long and involved job.  This
will cause one to need to restart all the way back on the first file,
or the top of a single file.

Therefore that Help information should mention that to do a undo, one
should enter a recursive edit to do it safely.
