         * Because we will modify the StrBuilder (replacing matches etc.) we need
         * to keep track of changes with respect to indexes. If there is a match
         * we will create a copy of the line and do the replacing on that line. We
         * however need to correct the indexes because we are adding or removing 
         * characters to the copy.

            copy.replace(matcher.start() + indexCorrection, matcher.end() + indexCorrection, replaceWith);

            indexCorrection = indexCorrection + replaceWith.length() - matcher.group().length();
