I see that Helmut has already reverted this part.

For the record, the original proposal did not appear to mention *- 
POSITION <ftp://ftp.csl.sri.com/pub/users/gilham/stream-definition-by-user.mail 

trivial-gray-streams calls this function STREAM-FILE-POSITION, as do  
CMUCL, SBCL, LispWorks <http://www.lispworks.com/documentation/lw51/LWRM/html/lwref-619.htm

CLISP calls it STREAM-POSITION <http://clisp.cons.org/impnotes/gray-gf-general.html

Some unification would be nice, and STREAM-POSITION is probably the  
better name because the operation can well be supported for non-file  
streams (flexi-streams uses the name FLEXI-STREAM-POSITION).
