string-filter: process filter or SRFI-13

[Tan Woon Kiong <tanwoonk@singnet.com.sg>]

Hi,

  I tried to define a process filter using procedure 'string-filter'.
However, SCSH 0.6.4  gave me the error.

Error: wrong number of arguments
       ('#{Procedure 8698 (string-filter in srfi-13)} '#{Procedure 14397
chuck-md5-tag})


SCSH seems to take definition of 'string-filter' as that defined in
SRFI-13's. How do I specify to SCSH that I want the process filter's
'string-filter' and not SRFI-13's?

Thanks,
  WK
