           Summary: WebBackForwardList should separate "has no current
                    index" from the integer value of the current index
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit2
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: beidson at apple.com


WebBackForwardList should separate "has no current index" from the integer value of the current index

While exploring https://bugs.webkit.org/show_bug.cgi?id=87417 we noticed much of the code is implicit and subtle, and much of that confusion is centered around using UINT_MAX to mark "No current item index"

Moving that out in to a separate bool will help clean things up a lot.
