Good idea - done. but as far as I understand the help for the function
format %S
,----
| %S means print any object as an s-expression (using `prin1').
`----
the second line is redy=undant, as the function format is doing it
anyway?
I'll leave the second line out and replace it with =value= instead, but
please correct meif I am missing something here.
Thanks,
Rainer
