There should always be a space between if and the opening paranthesis. The
command "git cl format" should take care of style issues like this.

This should be DCHECK(!text.empty()), as the text should never be empty if the
range is empty.

     return;
   size_t pos = range.GetMin() - offset;
   size_t n = range.length();
 
   DCHECK(pos + n <= text.length()) << "The text can not fully cover range.";
   if (pos >= text.length()) {
     NOTREACHED() << "The text can not cover range.";
     return;
   }
