    Let phex and phex_nz handle sizeof_l==1
    
    Currently, neither phex nor phex_nz handle sizeof_l==1 -- they let
    this case fall through to the default case.  However, a subsequent
    patch in this series needs this case to work correctly.
    
    I looked at all calls to these functions that pass a 1 for the
    sizeof_l parameter.  The only such case seems to be correct with this
    change.
