Git commit
commit b43108acb2cf60fcf0ad93ca07430c7b88d13202
Author: Guy Harris <guy@alum.mit.edu>
Date:   Sat Apr 16 17:52:11 2016 -0700

    Fix "2nd byte of optional tags bitmap" flag values.

    The presence bits field isn't made up of multiple bytes, it's a single
    32-bit field, so move the bit values up 8 bits so they don't collide
    with the values from the first byte.

    Prevents a crash with at least one 32.423 file.
