Did you read the point I made above and which the reporter conceded, namely
that such no-op replacements often indicate broken regexps?  Changing the
behavior to either silently ignore such cases or issue a vague "skipped
some replacements" message would make it more difficult to detect such
breakage and the affected buffer locations, with the only benefit stated so
far being to save someone typing "  +" instead of " +".
