    // there to bind the end of the negated pattern portion, and it's easier to
 | 
			
		||||
    // just stick it in now rather than try to inject it later in the middle of
 | 
			
		||||
    // the pattern.
 | 
			
		||||
    //
 | 
			
		||||
    // We can just always return the same end, and leave it up to the caller
 | 
			
		||||
    // to know whether it's going to be used joined or in parts.
 | 
			
		||||
    // And, if the start is adjusted slightly, can do the same there:
 | 
			
		||||
    // - if not isStart: nothing
 | 
			
		||||
    // - if traversal possible, but not allowed: (?:/|^)(?!\.\.?$)
 |

    // - if dots allowed or not possible: (?:/|^)
 | 
			
		||||
    // - if dots possible and not allowed: (?:/|^)(?!\.)
 | 
			
		||||
    //
 | 
			
		||||
    // But it's better to have a simpler binding without a conditional, for
 | 
			
		||||
    // performance, so probably better to return both start options.
 | 
			
		||||
    //
 | 
			
		||||
    // Then the caller just ignores the end if it's not the first pattern,
 | 
			
		||||
    // and the start always gets applied.
 | 
			
		||||
    //
 | 
			
		||||
    // But that's always going to be $ if it's the ending pattern, or nothing,
 | 
			
		||||
    // so the caller can just attach $ at the end of the pattern when building.
 | 
			
		||||
    //
 | 
			
		||||
    // So the todo is:
 | 
			
		||||
    // - better detect what kind of start is needed
 | 
			
		||||
    // - return both flavors of starting pattern
 | 
			
		||||
    // - attach $ at the end of the pattern when creating the actual RegExp
 | 
			
		||||
    //
 | 
			
		||||
    // Ah, but wait, no, that all only applies to the root when the first pattern
 | 
			
		||||
    // is not an extglob. If the first pattern IS an extglob, then we need all
 | 
			
		||||
    // that dot prevention biz to live in the extglob portions, because eg
 | 
			
		||||
    // +(*|.x*) can match .xy but not .yx.
 | 
			
		||||
    //
 | 
			
		||||
    // So, return the two flavors if it's #root and the first child is not an
 | 
			
		||||
    // AST, otherwise leave it to the child AST to handle it, and there,
 | 
			
		||||
    // use the (?:^|/) style of start binding.
 | 
			
		||||
    //
 | 
			
		||||
    // Even simplified further:
 | 
			
		||||
    // - Since the start for a join is eg /(?!\.) and the start for a part
 | 
			
		||||
    // is ^(?!\.), we can just prepend (?!\.) to the pattern (either root
 | 
			
		||||
    // or start or whatever) and prepend ^ or / at the Regexp construction.
