Ignore shell wildcards when determining next version.

Comment from Paul Foley:

  Problem: FD-OPEN calls NEXT-VERSION with the namestring;
  NEXT-VERSION calls EXTRACT-NAME-TYPE-AND-VERSION, which builds a
  "pattern" when it sees globbing characters in the name, and
  NEXT-VERSION promptly crashes when it tries to concatenate strings.

  Fix: Bind *IGNORE-WILDCARDS* to T in NEXT-VERSION (in
  fd-stream.lisp)
