 * An IndexedSourceMapConsumer instance represents a parsed source map which

 * input.
 *
 * The first parameter is a raw source map (either as a JSON string, or already
 * parsed to an object). According to the spec for indexed source maps, they
 * have the following attributes:
 *
 *   - version: Which version of the source map spec this map is following.
 *   - file: Optional. The generated file this source map is associated with.
 *   - sections: A list of section definitions.
 *
 * Each value under the "sections" field has two fields:
 *   - offset: The offset into the original specified at which this section
 *       begins to apply, defined as an object with a "line" and "column"
 *       field.
 *   - map: A source map definition. This source map could also be indexed,
 *       but doesn't have to be.
 *
 * Instead of the "map" field, it's also possible to have a "url" field
 * specifying a URL to retrieve a source map from, but that's currently
 * unsupported.
 *
 * Here's an example source map, taken from the source map spec[0], but
 * modified to omit a section which uses the "url" field.
 *
 *  {
 *    version : 3,
 *    file: "app.js",
 *    sections: [{
 *      offset: {line:100, column:10},
 *      map: {
 *        version : 3,
 *        file: "section.js",
 *        sources: ["foo.js", "bar.js"],
 *        names: ["src", "maps", "are", "fun"],
 *        mappings: "AAAA,E;;ABCDE;"
 *      }
 *    }],
 *  }
 *
 * The second parameter, if given, is a string whose value is the URL
 * at which the source map was found.  This URL is used to compute the
 * sources array.

    // (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.
