// for binding the start/end in either a joined full-path makeRe context
// (where we bind to (^|/), or a standalone matchPart context (where
// we bind to ^, and not /). Otherwise slashes get duped!
//
// In part-matching mode, the start is:
// - if not isStart: nothing
// - if traversal possible, but not allowed: ^(?!\.\.?$)
// - if dots allowed or not possible: ^
// - if dots possible and not allowed: ^(?!\.)
// end is:
// - if not isEnd(): nothing
// - else: $
//
// In full-path matching mode, we put the slash at the START of the
// pattern, so start is:
// - if first pattern: same as part-matching mode
// - if not isStart(): nothing
// - if traversal possible, but not allowed: /(?!\.\.?(?:$|/))
// - if dots allowed or not possible: /
// - if dots possible and not allowed: /(?!\.)
// end is:
// - if last pattern, same as part-matching mode
// - else nothing
//
// Always put the (?:$|/) 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.
