+    // - if dots possible and not allowed: ^(?!\.)

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