Hmmm.  memq returns #f, but sloppy-memq returns '() or any non-pair that
terminates the list.  Thus, if you use sloppy-memq, you can be fooled by
the following situation:
  (sloppy-memq 'a '(a))
  --> (a)
  (sloppy-memq 'a '(b c . (a))
  --> (a)
Thus, you can't tell whether a ceratin result means success or failure :-(

I figured out that sloppy-mem(q|v|ber) as well as the C counterparts are
not used throughout guile (except for within list.c itself).  Thus I
recommend to deprecate these functions.
