Snd 22.5:

s7: add vector-typer to return or set the type checking part of the 
vector element setter,
     and similarly hash-table-key-typer and hash-table-value-typer

checked: sbcl 2.2.5|6
   new ghostscript is unhappy with cmn eps files; version 9.55 is 
unhappy,
   9.52 is happy.  I think this is caused by negative origin bounding 
boxes
   which have worked fine for 30 years.
