const*const - what is the purpose of this?

Hi

I'm seeing declarations like this scattered around the SW module:
e.g. in sw/inc/swtable.hxx at line 301

  static SwTable * FindTable( SwFrmFmt const*const pFmt );

As far as I can tell from my limited C++ knowledge, this is the same as 
the more common definition:

  static SwTable * FindTable( const SwFrmFmt * pFmt );

i.e. the second const serves no purpose - or am I missing something?
