Quite often, performing query-replace, i just hit the [space] quicky
with no much attention. If i replace one string by mistake, i can
comeback to it with "^", but if i edit the string with "E" to reset it 
to its original value, the interactive query-replace session ends.

I found useful if we can undo such replacements without exiting the 
query-replace.

The attached patch implement such behaviour for `query-replace'.
Having this also working for `query-replace-regexp' would be very nice,
but harder to implement.
