Subject: [PATCH] fix handling of \\ in replacement string in s/// cmd of
 built-in sed

QString::replace() has no way of escaping capture group references,
so simply disarm double backslashes. of course this is broken, but
we'd need to reimplement it from scratch to fix it properly. "corner
case" ...
